Someone please help me will give brainliest!!!!!

I believe the fastest way to solve this problem is to take any two of the given points and to find the slope and y-intercept of the line connecting those two points.  

Let's choose the 2 given points (-3,16) and (-1,12).
Going from the first point to the second, the increase in x is 2 and the increase in y is actually a decrease:  -4.  Thus, the slope of the line connecting these two points is m = -4/2, or m = -2.

Now use the slope-intercept formula to find the y-intercept, b.

One point on the line is (-3,16), and the slope is m = -2.

Thus, the slope-intercept formula y = mx + b becomes 16 = -2(-3) + b.
Here, b comes out to 10.

So now we have the slope and the y-intercept.  Write the equation:

y = mx + b becomes y=-2x+10.  Which of the four given answer choices is the correct one?

Answer:

x - 10, I believe

Step-by-step explanation:

The differences between the x-values and the y-values are

1) 12 & -12 = 0

2) -4 & 0 = 4

3) 0 & 7 = 7

4) 10 & 0 = -10

Since the question asks which must be A factor of p(x) or the y-value, I would advise to look for the answer that helps you receive one of the differences shown above. That said, I would go with <em>x - 10.</em>

Does that help?
