Answer is D: y= -4x + 4
Reason
We know the formula is y=mx +b

Let’s find b. the chart shows you 0x 4y so your y intercept is 4.

Let’s find m which is slope
Slope is y2 - y1 over x2 - x1
Let’s use the first two pairs in the chart
8-4=4
-1 -0 =-1
So slope is - 4/1 simplified to -4

We can chose another pair to check
Using the bottom two pairs
0 - (-8) = 8
1 - 3 = -2
So slope is 8/-2 simplified to -4

So y= -4x +4

Answer:

You will find it.

Step-by-step explanation:

Replace the X value in each answer's formula with the table's value, then find the answer.

Ex: A. y = 4x + 4

if x = -1

=> y = 4.(-1) + 4 = 0 (not match y value in the table) => the answer is not A
