Quick... thanks!!!

  • graphing linear equations -

    Pick any two points on each line to draw it. For example where x = 0 and where y = 0
    I will do the first one
    3 y + 4 x = 12
    when x = 0 , y = 4
    so mark (0,4) on your graph paper
    when y = 0, x = 3
    so mark the point (3 , 0) on your graph paper
    Draw a straight line through those two points.
