__** 1.1: **__ List the math classes you have taken during high school. Write a few sentences describing your feelings toward math and why - either a good experience or a bad one. Think about what type of learner you are describe the best methods teachers use to help you understand the topics. Please describe your goals after this year - do you need this class to graduate and you are a senior, are you here for MCAS reasons, or what math class or classes do you plan on taking next year? I took algebra 1 freshman year and geometry sophmore year, now im a junior and taking algebra 2. Im not the best at math but im willing to learn so im going to try my best this year. i think i need only 3 math classes to graduate so after this one im good unless i fail but im planning on doing well. I dont plan to take math next year unless i really have to.

Look at the following, which is an example that has been worked out step by step. Explain in full sentences each step that was taken in the problem and why that step was chosen. Be clear about the step you are looking at, for example "going from line 1 to line 2, ..." All these steps should be written in your online journal. 1: first i subtract one of the Xs from both sides the get an equation with only one x. 2:always distribute whats behind the parethesis first. 3:subtract 5x from both sides get 40=1x-20 then add 20 to both sides and get 20=1x then i divide 1 and 20 and get x=1. 4:first i subtract 40 from both sides and get -1x=-60 then i divide 1 to both and get x=1 5:i divide -1 to both sides and get x=1 6:i pretend theres a one before x and divide one to 60 and get x=1 7:i distribute everything before the parenthesis. 8:i add all of them together which will be 34=34 9:

After spending time in class and at home solving a variety of equations, identify the type of problem that is the easiest for you to solve. Also identify the type of problem that you struggle with the most. Why is this type of problem the most challenging? Where do you make your errors most often? What tricks or reminders should you write here (in a different color) as a reminder to prevent that error in the future? I always make errors with problems involving fractions like the ones up there(#1 and 2) it always confuzes me and i never know how to do it.i should spend more time practicing fractions so this wont happen again. the easiest problem for me is the ones that you have to do the same to both sides then find the value of x to me those are easy unless they involve fractions.

List the following words and give a mathematical definition in your own words on your wikispace.
 * Linear Function-//a mathmatical equation that makes a straight line on the graph.//
 * Relation- //a connection one equation or solution has with another.//
 * Domain//-a set of all possible values of a varible of a function.//
 * Range//-the diffrence between the highest and lowest value of a set of data.//
 * increasing//-getting bigger.//
 * Decreasing-//getting smaller.//
 * Slope//-a number the X that tells if the line goes up or down.//
 * Intercept-//the number after the slope y=mx+b//
 * Degree-//a mesurement of an angle.//

__** 1.5: **__Read pages 67-69 to understand what a relation, linear function, and function notation is then answer the following questions.

//a relation is a pair when two are together,of input values with output values. a linear function is y=mx+b and when the graph// is a line.
 * In your own words describe what a relation is and a linear function is.

//A function is (1,1) a non function is (1,2) and that is not a function because its not constant and not the same number.//
 * Give an example of a relation that is a function and a relation that is not a function. Represent the relation graphically and as a set of coordinate points. Explain why your second example is not a function. **__You cannot use example 2 on page 68 as your example.__**

//f(x)=2x-3 slope is 2x and y-intercept is -3.//
 * Give an example of a linear function written in function notation. Identify the slope and y-intercept of the function. Graph the function and label at least 3 coordinate point that are on the line. **__You cannot use example 4 on page 69 as your example.__**

__** 1.6: **__Below there is a document which 4 linear graphs shown and 6 linear equations given. In a paragraph, describe how you matched each equation to its matching graph and the order in which you matched them. What graphical features did you look at or which parts of that equation did you focus on?

One i matched with graph B,two i matched with D, three is graph D, four is graph A,five is graph A,six is graph C,seven is graph D and eight is graph A. I mostly focus on the signs,like if the equation is negative or positive and if its a fraction or not.

__** 1.8: **__Using the graph below:
 * Complete the following table
 * Write a paragraph describing the walking pattern shown. Use as much detail as possible so that some one would be able to recreate this graph from your description.
 * Table:**
 * time in minutes || speed in miles per hour ||
 * 0 || 0 ||
 * 1 || 30 ||
 * 4 || 30 ||
 * 4.25 || 0 ||
 * 5 || 0 ||
 * 6 || 40 ||
 * 8 || 40 ||
 * 9 || 20 ||
 * 11.5 || 20 ||
 * 12 || 20 ||

Answer the following questions:
 * When is Anne driving the fastest? Explain how you found your answer.//at 5 minutes because the lines all the way 40.//
 * What time is Anne stopped? Explain how you found your answer. //at 4.25 because it says it on the table and the line is at 0.//
 * When is Anne's speed decreasing? Explain how you arrived at your answer.//at 12 minutes,because the lines is lower.//
 * What is Anne's speed at 7 minutes?//40 miles per hour.//
 * At what approximate time is Ann driving 35 mph?//around 6 .//
