Hero · Answer

The equation of a line is y = mx + b right?

katherine · Answer

Yes!

Hero · Answer

And point M is (x,y) = (-2,1) and the slope is m = -4 correct?

katherine · Answer

Correct

Hero · Answer

So in other words, x = -2, y = 1 and m = -4. Do you think you might be able to enter those values in to the equation of the line y = mx + b?

katherine · Answer

yea, that's my problem. idk how lmao

Hero · Answer

So for y = mx + b, you don't know how to replace x with -2, replace y with 1 and replace m with -4?
