Answer
Rate change = 1
Explanation:
Rate change means the slope on the graph
Slope = rise / run
Rise = y2 - y1
Run = x2 - x1
Slope = y2 - y1 / x2 - x1
From the graph, Given the picked points
(5, 5) and (-5, -5)
x1 = 5, y1 = 5, x2 = -5, and y2 = -5
Slope = -5 - 5 / -5 -5
Slope = -10 / -10
Slope = 1
Hence, the rate change is 1
