  1. Plotting graphs

  2. Linear graphs(x = 0, y = 0, method) Click to continue +y • y = 2x +4 • When x = 0 • y = 0 + 4 = 4 • When y = 0 • 2x + 4 = 0 • 2x = - 4 • X = - 2 0 +x -x -y

  3. Click to continue Linear graphs(x = 0, y = 0, method) simultaneous equations x – y = 2 and 2x – y = 6 x – y = 2 (y=0, x = 2) ( x = 0 y = -2) 2x – y = 6 (y =0, x = 3) ( x =0, y = -6) X = 4, y = 2 2x – y = 6 X – y = 0

  4. Quadratics y = x2
