Question

can someone tell me how to solve this

Answer 1

x | y
-3 |-3
0 | 3
1 | 5

Find the average rate of change for the given function from x = -3 to x = 1.
A) 2

B) -3

C) -1

D) -2

Answer 2

Standard form of the function: y = ax + b. Find the rate of change (a).
When x = 0 -> y =3, then, b = 3
When x = 1 -> y = 5 = a + 3 --> a = 5 - 3= 2.
y = 2x + 3.
