__**On your wikispace**__, describe the relationship between different pairs of lines and their slopes as it relates to the number of intersections (solutions) that the system of equations will have. Be sure to discuss all 3 graphs and how they are similar or different.

‍__ 2.2: __
Describe the 3 different methods for solving (finding a solution) to a system of equations. Why/When would you choose one method over the another? What are you looking for in each system to determine the best method? Discuss any tricks or special techniques to remember when solving each of the methods. //The 3 types of methods for solving are subistitution,elimination and graphing. I would choose the one that is easiest and most appropriate like if i need to find the slope or something i would plot the points and graph it. but to me substitution is the easiest because i can solve it faster. I'm looking for a variable to be substituted if it gives me one and if there's two variables then i use the elimination option.//

Look at the graph below. Both functions represent two different bank accounts.


 * The blue linear function represents a bank account where a person deposited $1000. This person then deposits an additional 100 dollars at the end of each year.**


 * The red linear function represents a bank account where a person deposited $1050. This person then deposits an additional 75 dollars at the end of each year.**

Compare and contrast the two bank accounts in your online journal by answering the following questions:
 * Write a function that represents the red linear function.red: //f(x)=1050x+75 blue:f(x)=1000x+100//
 * What is the y-intercept of each function? Explain in the context of the situation.//red://75 //and it represents the amount that was deposited into the bank per year.blue:100.//
 * What is the slope of each function? Explain in the context of the situation.red://1050 and it represents the money the person deposited into the bank account before the 75.blue:1000.//
 * Which account is better? Is this always true? Be specific, using dates and account values from the graph to support your argument. //The red line because it has more money to start with so less money is being put in at the end of each year and it still has as much as the blue one does.//
 * Which account would you choose when opening to save up for your college in a few years and why? //the red because i would want to start out with more money instead of having to pay more later.//
 * Would you choose that same account to start your child's college fund (if you had a child) and why?//Yes because i feel like it would be easier especially at the end of the year,maybe ill have more money when i start the account then at the end of the year.//
