Question

Which equation describes the

function table?

A b = a - 1
B a = b - 1
C b = 3a + 3
D b = 2a + 1

Answer 1

Answer: Choice D. b = 2a+1

Step-by-step explanation:

Each time b goes up by 4, 'a' goes up by 2. The rate of change or slope is 4/2 = 2. This lets us see that the answer must be choice D, as no other answer choice has 2 as a slope.

Answer 2

The answer is no.d b= 2a + 1
