Math problem help me. I got it wrong I think
lukranit [14]

Answer:

The answer is B

Step-by-step explanation: After solving this equation using y=mx+b

I got y=-4x+7

So they give us the slope which is negative 4

so you would throw in the x coordinate with the slope and multiply to get y=-12+7

then you would use the y coordinate to substitute the Y

-5=-12+7

i add twelve on both sides and end up with the y intercept being 7]

so I add them into the equation and got y=-4x+7
