-In order to find this, you need to find the slope first. -Since the x-intercept is (4,0) and the y-intercept is (0,-2), we can use (y-y1)/(x-x1). -So, (0 - -2)/(4 - 0) = 2/4 = 1/2 (this is the slope) -Using y=mx+b, where m= the slope and b=the y-intercept, plug in 1/2 for m and -2 for b -Now the equation is y=1/2x -2
