2 Yesterday’s Homework Any questions?
Please pass your homework to the front. Make sure the correct heading is on your paper. Is your NAME on your paper? Make sure the homework is 100% complete. Incomplete work will NOT be accepted.

3 Solving Linear Inequalities
Heading 2/24/2019 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 Rewrite the equation. Rewrite the equation. Plug in x and y. Plug in x and y. Simplify. Simplify. Is this true? Is this true?

5 Notes Determine whether the ordered pair is a solution to the equation. Ex. Now you try. x y x y x y Rewrite the equation. Rewrite the equation. Plug in x and y. Plug in x and y. Simplify. Simplify. Is this true? Is this true?

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. Dashed Below

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

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

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

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

12 Notes Graph. Ex. 1) Put in slope-intercept form. Vertical Line
Now you try. Graph. Ex. 1) Put in slope-intercept form. Vertical Line 2) Graph. Find m and b first. Solid Left of line 3) Solid or Dashed? 4) Shade above or below the y-intercept.

13 Summary To graph a linear inequality just graph like you would a regular equation. If there is a bar it’s a _____ line, if there is no ____ its dashed. If the symbol is greater than shade ______, if it is ____ than shade below. solid bar above less

14 Today’s Homework Rules for Homework Pencil ONLY.
Must show all of your work. NO WORK = NO CREDIT Must attempt EVERY problem. Always check your answers.

15 Homework 6.6 Determine whether the ordered pair is a solution to the inequality. Graph the inequality.

16 Ticket Out the Door Complete the Ticket Out the Door without talking!!!!! Talking = time after the bell! Put your NAME on the paper. When finished, turn your paper face DOWN. Graph.
