Leslie analyzed the graph to determine if the function it represents is linear or non-linear. First she found three points on
the graph to be (-1,-4), (0, -3), and (2,5). Next, she determined the rate of change between the points (-1, 4) and (0,
-3-(-4) 1
5-(-3) 8
-3) to be 0-(-1- 1 - 1 and the rate of change between the points (0, -3) and (2,5) to be 2-0 2
- 4. Finally, she
concluded that since the rate of change is not constant, the function must be linear. Why is Leslie wrong?
