Question

Need Help/Confirmation:

Use the Table Below:
X | Y
-1|5
1|3
4|0

Find the average rate of change from x = -1 to x = 4

I put 3. The choices are:
a) -3
b) -1
c) 1
d) 3

Answer 1

just subtraction

Answer 2

by average rate of change means the slope
so use the slope formula (y2-y1)/(x2-x1)

(-1,5) (4, 0)
(x1,y1) (x2,y2)

plug in the points into the equation and solve

Answer 3

Oh! So that would mean the answers -1? B?
