1. Graph Inequalities On Coordinate Plane
Denise Langley

2. Review Linear Equation
Remember How to graph:
y = -2x + 3
y-intercept: 3
Slope: -2/1

3. b = 3
y = -2x + 3
m = -2/1

4. y > -2x + 3
First, graph the boundary line. Graph it just like an equation with y-intercept and slope, or x- and y-intercepts.

5. y > -2x + 3 Since it is greater than or equal
b = 3
y > -2x + 3
m = -2/1
Since it is greater than or equal
to the line, fill in the line, plus
all values greater than (above)
the line.

6. y < -2x + 3 Since it is less than or equal
b = 3
y < -2x + 3
m = -2/1
Since it is less than or equal
to the line, fill in the line and
shade all values less than
(below) the line.

7. y < -2x + 3 The boundary line is not
m = -2/1
Show the line is not
included by making it
dashed (unshaded)
The boundary line is not
included since it is not equal.
Shade all values less than
(below) the line.
