Answer:
-1
Step-by-step explanation:
In the picture attached, the question is shown.
To compute the rate of change of the linear relationship we need two points, (x1, y1) and (x2, y2), and the next formula:
rate of change = (y2 - y1)/(x2 - x1)
Selecting points (0,3) and (1,2), notice that other selections are also possible, and replacing them into the equation we get:
rate of change = (2 - 3)/(1 - 0) = -1
