Find the slope of the line passing through the points (-5, 3) and (7,9).
dybincka [34]

Answer:

\huge\boxed{slope=\dfrac{1}{2}=0.5}

Step-by-step explanation:

The formula of a slope:

m=\dfrac{y_2-y_1}{x_2-x_1}

We have the points

(-5;\ 3)\to x_1=-5;\ y_1=3\\(7;\ 9)\to x_2=7;\ y_2=9

Substitute:

m=\dfrac{9-3}{7-(-5)}=\dfrac{6}{7+5}=\dfrac{6}{12}=\dfrac{6:6}{12:6}=\dfrac{1}{2}
