Answer:
B. [tex] -\frac{9}{2} [/tex]
Step-by-step explanation:
Rate of change of y with respect to x, can be calculated using any two of the pairs of values of the table, say, (-2, 12) and (0, 3).
Rate of change = [tex] \frac{y_2 - y_1}{x_2 - x_1} [/tex]
Let,
[tex] (-2, 12) = (x_1, y_1) [/tex]
[tex] (0, 3) = (x_2, y_2) [/tex]
Plug in the values
Rate of change = [tex] \frac{3 - 12}{0 - (-2)} = \frac{-9}{2} = -\frac{9}{2} [/tex]
