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.
