​(Type a whole​ number.)

Answer 1

Explanation:

The rate of change is the slope of the line. You know it's negative because the line is slanting down. Pick any 2 points on the line and find the slope.

Use (0,25) and (4,5)

Slope = Δy/Δx = (5-25) / (4-0) = -20/4 = -5

Rate of change is -$5,000/yr

Note: the y axis is labeled in thousands of dollars
