The GCF of 20x^4 and 6x^3 would be " 2x^3 "
Finding the slope using two points:
The formula for slope is
In this case you have the points (-3, 5) and (4, 5):
^^^Plug these numbers into the formula for slope...

0
^^^This is your slope

5/8 - 17/8
combine : 5-17 / 8
subtract : 5 - 7 = -12
-12/8
apply fraction rule ( -a/b = - a/b) : - 12/8
cancel common factor 4
answer : - 3/2
I hope this helped
