Write the point-slope form of the given line that passes through the points (0, 3) and (4, 0). Identify (x1, y1) as the x-intercept of the line.

the x intercept is where the line crosses the x axis or where y=0 (x,0) is the x intercept oh, look (4,0) the x intercept is x=4 anyway point slope form y-y1=m(x-x1) for a line passing throuh (x1,y1) and slope is m find slope slope between (x1,y1) and (x2,y2) is (y2-y1)/(x2-x1) given (0,3) and (4,0) slope=(0-3)/(4-0)=-3/4 a point is (4,0) y-0=-3/4(x-4) y=-3/4(x-4) xintercept is x=4
