Question

What would the constant rate of change be?

A) -8
B) 1
C) can’t tell from this problem
D) 12

Answer 1

- 8

Explanation:

An equation in the form y = mx + c ( m is the slope and c is the y- intercept )

Has a constant rate of change = m

given

`a_(n)` = 12 + (n - 1)(- 8) ← distribute and simplify

y = 12 - 8n + 8

y = - 8n + 20 ← in the form y = mx + c

with constant rate of change = - 8
