Answer:
m = -11
Step-by-step explanation:
First, use the slope format: y2 - y1/x2 - x1
-21 and -10 being y2 & y1, while 4 and 3 being x2 & x1:
-21 - (-10)/4 - 3
(Note: replace - (-10) with + 10 to make it easier)
Subtract -21 and -10, then 4 and 3.
You will get -11/1, which if simplified, is -11
Hope this helps!
