Question

Find the slope of the line passing through the points (0, 4) and (–8, –1). A. -8/5 B. -5/8 C. 5/8 D. 8/5 Find the slope of the line passing through the points (1, –5) and (4, 1). A.2 B. -4/5 C. 5/4 D.-2

Answer 1

Hi there!

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

$SLOPE=\frac{Y_2-Y_1}{X_2-X_1}=\frac{RISE}{RUN}$

$\frac{(-1)-4}{(-8)-0}=\frac{-5}{-8}=\frac{5}{8}$

Slope is 5/8.

Final answer is C. 5/8.

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

$SLOPE=\frac{Y_2-Y_1}{X_2-X_1}=\frac{RISE}{RUN}$

$\frac{1-(-5)}{4-1}=\frac{6}{3}=2$

Slope is 2.

Final answer is 2.

Hope this helps!

Have a nice day! :)

:D

Thank you! :)

Answer 2

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
