Anyone can help?? I need it done before 9am please!!

The answer is below

Explanation:

The equation for a linear line graph is given by:

y = mx + b, where y and x are variables, m is the slope of the graph and b is the y intercept (that is value of y when x is zero).

The slope (m) of a line passing through two points is given by:

A) The first line passes through the point (0, 0) and (10, 60). It is represented as (time, velocity). Hence the slope is:

B) The second line passes through the point (10, 60) and (15, 60). Hence the slope is:

C) The third line passes through the point (15, 60) and (40, -40). Hence the slope is:

D) The third line passes through the point (40, -40) and (55, 0). Hence the slope is:
