Answer:
-11
Step-by-step explanation:
y2-y1/x2-x1
Take the y-value from the second pair of coordinates and subtract it from the first y-value, then do the same for the x-coordinates. Take the result from subtracting the y-values and put it over the result from subtracting the x-values. I got 11/-1, which is -11.
I hope this helps :)
