Solution:
Given that,
We have to find the rate of change between (-3,6) (0,-3)
The rate of change is given as:
[tex]Rate\ of\ change = \frac{y_2-y_1}{x_2-x_1}[/tex]
From given,
[tex](x_1, y_1) = (-3, 6)\\\\(x_2, y_2) = (0, -3)[/tex]
Substituting the values we get,
[tex]Rate\ of\ change = \frac{-3-6}{0+3}\\\\Rate\ of\ change = \frac{-9}{3}\\\\Rate\ of\ change = -3[/tex]
Thus rate of change is -3
