Answer:
D
Step-by-step explanation:
The x-values are evenly-spaced, so any linear function table will have constant differences between the y-values. Here are the y-differences for the different options:
A 1, 2, 4
B 1, -1, 3
C -1, -2, 1
D 5, 5, 5 . . . . this represents a linear function

Answer:
The answer is B. (4) Because a coeffecient is the number next to the letter.
We have one of those equations already solved for y, so let's sub that one into the other one and solve the equation in terms of x only:

. We will simplify that and at the same time bring the 6 over by subtraction to get a polynomial set to equal 0 that we can factor.

. We will factor that to get (x-3)(x+1) for x values of x = 3 and x = -1. a above is the choice that has the x values we need, -1 and 3.
