Write an equation in slope-intercept form for the line that passes through (4, 4) and has a x-interceptof 3.

We have two points (4, 4) and the x intercept. ( 3, 0)......we need to find the slope....so we have

slope = m = [ 4 -0 ] / [ 4 - 3 ] = 4/ 1 = 4

So....using the slope and either point - I'll use (3, 0) - slope-intercept form is

y = mx + b

First.....write in point-slope form

y - 0 = (4)(x - 3)

y = 4x - 12

And that's point-slope form
