Question

Find the slope of the line that goes through the points (–4, 1) and (8, –5).

Answer 1

-5-1/8-(-4)
-6/12
-1/2

Answer 2

`(-1)/(2)`

Explanation:

Slope is the change in y over the change in x.

The ordered pair is in the form (x,y). The first number is the x value and the second number is the y value.

for y;

-5 - 1 = -6

for x:

8 - (-4)

8 + 4

12

`(-6)/(12)` Which is the same as
`(-1)/(2)` if we divide the top and bottom by 6
