Solving Linear Inequalities
TSWBAT: graph a linear inequality.
Students graph a linear equation and compute the x- and y- intercepts (e.g., graph 2x + 6y = 4). They are also able to sketch the region defined by linear inequality (e.g., they sketch the region defined by 2x + 6y < 4).

4. Notes
Determine whether the ordered pair is a solution to the inequality.
Ex.
Now you try. x y x y x y

6. Notes Steps to Graphing Linear Inequalities
Write the equation in slope-intercept form.
Graph the y-intercept and slope.
Draw the line (solid or dashed).
Dashed line
Solid line
4. Shade above or below the y-intercept.
Above y-intercept
Below y-intercept

7. Notes Graph. Ex. 1) Put in slope-intercept form.
2) Graph. Find m and b first.
3) Solid or Dashed?
b = beginning
m = move
4) Shade above or below the y-intercept.
