y - y₁ = m(x - x₁)
y - (-1) = 4[x - (-3)]
y + 1 = 4(x + 3)
y + 1 = 4(x) + 4(3)
y + 1 = 4x + 12
- 1 - 1
y = 4x + 11

The answer is B.

MA_775_DIABLO [31]

Answer:

$x^{2}$ +5x-36

Step-by-step explanation:

I will use the box method, and I hope it helps you!

After looking at the picture, this is not the answer quite yet.

$x^{2}$ $+9x$ $-4x\\$ $-36$

Subtract 4x from 9x.

9x-4x=5x

So, the answer will be $x^{2}$ +5x-36
