2x + 3y = 1200 3y = -2x + 1200 y = -2/3x + 400......slope = -2/3....y int = (0,400)...x int = (600,0)
start at (0,400)...and since ur slope is -2/3, go down 2 spaces, and to the right 3 spaces...plot this point...then go down 2, and to the right 3...plot this point....keep doing this and u should cross the x axis at (600,0).
