Question

Find the slope of the line without graphing using the 2 points below.

(-2, -1) & (-8 , 11)



m = _______

Answer 1

m = -2

Explanation:

1. use the slope formula --> (y2-y1)/(x2-x1)

2. (11 -(-1))/(-8 -(-2))

3. 12/-6

4. m = -2

Answer 2

The slope is -2

Explanation:

We can use the slope formula

m = ( y2-y1)/(x2-x1)

= ( 11- -1)/( -8 - -2)

( 11+1)/( -8+2)

12/-6

-2
