Write an equation in slope-intercept form for the line that passes through (4, 4) and has a x-interceptof 3.
+128448 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
