How do you graph the line y = 3x + 2.

  • Math - ,

    y - intercept

    for x = 0

    y = 3 * 0 + 2 = 0 + 2 = 2


    x - intercept

    3 x + 2 = 0

    3 x = - 2

    x = - 2 / 3


    Plot coordinate system.

    Them mark points :

    x = 0 ; y = 2

    and

    x = - 2 / 3 ; y = 0


    Then drawe straight line.
