Question

Find the equation of the line with slope -4 and going through point (3,8) and then convert it to slope intercept form “y=Mx+b Please help ?

Answer 1

y=-4x+8

Explanation:

Since the slope is given to you, you already know part of the equation. slope is equal to mx. So y=-4x. the B in y=mx+b is y-intercept. The y intercept is where the line comes in contact with the y axis. On a coordinate plane the y intercept would be Y [ex; (x,y)]. It gives you (3,8) so the y intercept would be +8 since the point is positive and not negative.
