1. 1.What is the equation of a line passing through the point (8, -3) and having no slope? 2.If the slope of a line is -5 and the line contains the points (2, 3) and (x, -7), what is the value of x?

2. Lesson 1.7 Solving Inequalities in One Variable

3. Write, solve and graph linear inequalities in one variable Solve and graph compound linear inequalities in one variable.

4. A company manufactures a small gear for a car. The cost of producing the gear is C = 40x+868. The money earned, or the revenue, from selling x gears is R = 54x. In order to make a profit, the revenue must be greater than the cost. How many gears does the company need to sell to make a profit???

5. Inequalities are solved in exactly the same way equations are solved except Reverse the inequality sign if you multiply or divide by a negative number

6. Solve the inequality: Combine like terms Subtract 6 from both sides Divide by -6 and flip the inequality!

7. ANS: y>-2

8. Inequalities in one variable are graphed on a number line. Open circle Closed circle

9. Solve and graph:

10. Write an inequality when given the graph

11. Solve compound inequalities A compound inequality is a pair of inequalities joined by “and” or “or”. For example: or

12. Solve and graph the compound inequality: or When you solve a compound inequality involving or, find the values that make either inequality true.

13. Solve and graph the compound inequality: and When you solve a compound inequality involving and, find the values that make both inequalities true.

14. Solve and graph the compound inequalities: and

15. Solve and graph the compound inequalities: or

16. Big hint to remember!! An “or” graph typically looks like this: An “and” graph typically looks like this: But not all the time!

17. Write a compound inequality given the graph:

18. But not all the time! Graph on a number line: or

19. But not all the time! Graph on a number line: and
