Answer:
M = - 3
Step-by-step explanation:
Find the Slope:
Slope is equal to the change in y over the change in x
, or rise over run.
m = [tex]\frac{change in Y}{change in X}[/tex]
The change in x is equal to the difference in x-coordinates (also called run), and the change in y is equal to the difference in y-coordinates (also called rise).
m = [tex]\frac{y_{2}-y_{1} }{x_{2}-x_{1}}[/tex]
Substitute in the values of x and y into the equation to find the slope.
m = [tex]\frac{3-(9)}{4-(2)}[/tex]
Simplify.
m = [tex]\frac{-6}{2}[/tex]
m = -3
