Answer:
Option B : 1/2 is the correct answer.
Step-by-step explanation:
Given ordered pairs are;
(3, 6) and (5, 7).
We have to find the rate of change which is also known as slope.
Slope is the steepness of a line.
The formula of slope is given by;
m = [tex]\frac{y_2-y_1}{x_2-x_1}[/tex]
m = [tex]\frac{7-6}{5-3}[/tex]
m = [tex]\frac{1}{2}[/tex]
Hence,
Option B : 1/2 is the correct answer.
