1. Explain what the slope represents in this situation.

please help

The slope is how much he saves per week (In this case it would be $5 per week)

Step-by-step explanation:

Slope is rise/run or change in y/change in x

In this graph, from x=0 to x=8, the rise or change in y is 40$ and the run or change in x is 8 weeks. So the slope is $40/8 weeks, or $5/week

location: point 0

step-by-step explanation:

well, -8 to 10 on a number line is 18 spaces.

1/9 of 18 is 2.

so, 4/9 of 18 must be 8.

8 spaces from -8 (a) is 0.

so, 4/9 of the way from -8 to 10 is 0!
