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:
Connie starts with $9 and Chris starts with $27.
Step-by-step 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.
