1. Graph Inequalities On Coordinate Plane

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

3. Y = 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
M = -2/1
Since it is Greater than or
equal to the line, it is the line,
plus all values greater (above) the line.

6. Y < -2x + 3 Y = 3 M = -2/1 It is the Line, plus
Shade LESS, below the line

7. Y < -2x + 3 Y = 3 M = -2/1 Show the line is not
included by making it
dashed (unshaded)
The boundary line is not included
as it is not equal to the line,
but everything less.
