Answer:
m = -12.50, b = 1,500; The first option.
Explanation:
To figure out the slope I used the equation, y1 - y2 / x1 - x2, to get the answer -12.50.
For the y-intercept ( b ), I just looked at the data table and where there was a zero in the X side of the Y there would be the, b, or y-intercept.
