Question

Connie and Chris are saving money to go to a concert. Each friend starts with some money and saves a specific amount each week. Connie wrote an equation to show the total, y, she has saved at the end of each week, x. y = 6x + 9 Chris made a graph to show the total he has saved at the end of each week. Compare the amount that each friend has when both friends start saving. Select the correct answer from the drop-down menu to complete the statement. Chris starts with $ and Connie starts with $.

Answer 1

ok. you're looking for the slope intercept, or how much each of them had before they started saving. Chris had $27, as that is where his line crossed the y axis, and Connie, when graphed, intercepted at $9.

Answer 2

Connie starts with $9 and Chris starts with $27.

Explanation:

Connie's savings is given by the equation y = 6x + 9

Here, the variable x represents the end of each week.

So, to find Connie's initial savings, put x = 0 and solve for y.

y = 6(0) + 9

y = 9

Hence, Connie's starting amount is $9.

To find Chris's starting amount, let's find the y value at x = 0 from the graph.

Clearly, it is 27 as (0, 27) is the first point of the graph.

Hence, Chris's starting amount is $27.
