Answer:
-9/4
Step-by-step explanation: The equation to find slope is y2-y1 over x2- x1
So you need to take your 4 (y2) and your -5(y1) and you are going to subtract 4--5, two negatives make a positive so you add it and it becomes 9. Then you need to take -2 (x2) and 2 (x1) and subtract them -2-2 =4
That gives you -9/4.
I hope this helps :)
