Explain why the points (0,8) do not lie on the line y= 4x+9 ? (3 marks)
To see if (0,8) lies on the line y, substitute 0 (the x coordinate) into y = 4x+9 so y=4(0)+9 y=4(0)+9 therefore y= 0+9 = 9since the output (9) is not the same as the respective coordinate (8), (0,8) does not lie on the line y= 4x+9check by drawing a rough graph
