Answer:

Step-by-step explanation:
The slope-intercept equation takes the form

Where m is the gradient, and c is the y-intercept.
If we assume we are plotting a graph where the X axis is time, and the y axis is distance, and we know our time value starts at 40, then we can say that our y intercept value is 40.
Next, let's figure out how far she has travelled. 130-40 = 90, and she has travelled this distance in 30 seconds, so dividing 90 by 30, we know that she is travelling 3 feet a second. This leaves us with a gradient of 3.
Putting these two values together, we can find the final form of the equation to be:
