Y = mx + b slope(m) = -3/4 (3,3)....x = 3 and y = 3 now we sub and find b, the y int 3 = -3/4(3) + b 3 = -9/4 + b 3 + 9/4 = b 12/4 + 9/4 = b 21/4 = b.....or 5.25 for graphing purposes
so ur equation is : y = -3/4x + 21/4
ur y int = (0,21/4) or (0,5.25)
ur x int can be found by subbing in 0 for y and solving for x y = -3/4x + 21/4 0 = -3/4x + 21/4 3/4x = 21/4 x = 21/4 * 4/3 x = 84/12 = 7.....so ur x int is (7,0)
so plot ur points (7,0) and (0,5.25)....now start at (0,5.25) and since the slope is -3/4, come down 3 spaces and go to the right 4 spaces, then down 3, and to the right 4 and u will eventually cross the x axis at (7,0)
