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=(Y_2-Y_1)/(X_2-X_1)=(RISE)/(RUN)`

`((-1)-4)/((-8)-0)=(-5)/(-8)=(5)/(8)`

Slope is 5/8.

Final answer is C. 5/8.

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

`SLOPE=(Y_2-Y_1)/(X_2-X_1)=(RISE)/(RUN)`

`(1-(-5))/(4-1)=(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
