Find the average rate of change over the interval 7 less than or equal to X less than or equal to 10, of the function defined by the table X. Y.
1 1
4 16
7 49
10 100

A. 8
B. 17
C. 5
D. 11

B. 17

Step-by-step explanation:

The average rate of change is:

m_avg = (y₂ − y₁) / (x₂ − x₁)

m_avg = (100 − 49) / (10 − 7)

m_avg = 17

y -5 = (-1/4)(x + 8)

step-by-step explanation:

if you was gonna solve for a, a is a   < -12
