The formula to find it is (y2-y1)/(x2-x1)
Substituting 4 in for y2, 0 for x2, -1 for y1, and -8 for x1
Thus, doing the subtraction you get 5/8

Hi there!

1. (0,4) and (-8,-1)

[tex]SLOPE=\frac{Y_2-Y_1}{X_2-X_1}=\frac{RISE}{RUN}[/tex]

[tex]\frac{(-1)-4}{(-8)-0}=\frac{-5}{-8}=\frac{5}{8}[/tex]

Slope is 5/8.

Final answer is C. 5/8.

2. (1,-5) and (4,1)

[tex]SLOPE=\frac{Y_2-Y_1}{X_2-X_1}=\frac{RISE}{RUN}[/tex]

[tex]\frac{1-(-5)}{4-1}=\frac{6}{3}=2[/tex]

Slope is 2.

Final answer is 2.

Hope this helps!

Have a nice day! :)
