Question

Passes through (4,-1), slope =-3

Answer 1

the slope intercept form of this would be y=*3x-1. The formula for slope intercept form is y=mx+b, where m is the slope and b is the y-intercept. I this problem, the y-intercept is -1, so you would plug in -1 for b, so the equation is y=mx-1. The slope is -3, so you plug that in for m, so the equation now becomes y=-3x-1. Hope that helps!!

Answer 2

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