Question

Evan performed an experiment testing how different wind speeds affect how fast a small cart will roll down a ramp. His data from the experiment is shown in the graph below.

Answer 1

-0.25x + 9

By looking at the graph, we can see that the y-intercept is between 8 and 10.

Slope intercept equation:

y=mx+b

Where;

b= y-intercept ( where the line crosses the y axis )

m= slope ( rise / run)
