paledeer · Answer

The answer would be C by process of elimination
But here is how you would do these in the future.

Slope-Intercept form is$$y=mx+b$$
With M being slope, and B being Y-intercept.

Now to find your B you have to set it up like so

-2= -4(0)+b
Then you do simple algbra to get -2=b

Then you just add in and build it. Y= -4x -2
