What is the slope of the line passing through the points (-5,9) and (2,-12)
1 answer:
Answer:
-3
Step-by-step explanation:
To find the slope of a line given two points, we use:
.
Or you could line up the points vertically and subtract the points vertically, then put 2nd difference over 1st difference.
That looks like this:
( 2 , -12)
-( -5 , 9 )
----------------
7 -21
So the slope is -21/7 which gives you -3.
