      if you want to find where a line cuts the y axis then let x = 0 and see what y value comes out (0,?) and vice versa if you want to find where a line cuts the X axis then let y = 0 and see what x value comes out (?,0) Hope this helps!!

      1. write down the equation of the line. e.g. LINE; 3x + 2y = 12

      2. For crossing the X axis ; let y = 0 3x + 2(0) = 12

      3. Solve this equation 3x + 0 = 12

      3x = 12

      x = 4

      So if x=4 and you know y = 0 then the point you want is (4,0)

      For crossing the y axis, let x = 0

      then you get
