y<2x+4

y>5

How do I do this?

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.
