I trust you know about y = mx + b
Realize that when you are given the x or y intercepts, you are really just given two points, in your case the points (4,0) and (0,2)
So it is easy to find the slope, (20)/(04) = 1/2
Take it from there
Determine the pointslope form of the line and the slopeintercept form of the line with xintercept = 4 and yintercept = 2
