I'm graphing linear inequalities...it says I need to do:
y<2x+4
y>5
How do I do this?

  • Algebra 1 -

    Y < 2X + 4.

    Y > 5.

    When graphing inequalities, we actually, graph the boundary line.
    For instance, we graph Y = 2X + 4 for
    the 1st inequality and Y = 5 for the
    2nd inequality. If no equal sign is
    included in the inequality, the boundary is represented by a dotted line.

    You should realize that Y = 5 is a hor.
    line and Y equals 5 for all values of X: (-2, 5), (0, 5), (2, 5).

    Y = 2X + 4. (-2, 0), (0, 4), (2, 8).
    Draw a dotted line through these points. Since the inequality sign is a
    less than(<), the solution is all points below the line. The points on the line should not satisfy the inequality.
