Presentation Transcript

### Review topics

### Inequalities and their Graphs

Inequalities

Graph each inequality.

1. x > –5 2.y ≤ 0

3. Write –6x + 2y = –4

in slope-intercept form,

and graph.

y = 3x – 2

What is a good definition for Inequality?

An inequality is a statement that two expressions are not equal

Terms you see and need to know to graph inequalities correctly

< less than

Notice open circles

> greater than

≤ less than or equal to

≥ greater than or equal to

Notice colored in circles

x

Objective - To graph linear inequalities in the coordinate plane.Number Line

Coordinate Plane

-4 -3 -2 -1 0 1 2 3 4

x = 3

Determine whether the given point is a solution

to the inequality -2x + 3y < 9.

1) (2, -3)

Yes, (2,-3) is a solution.

2) (3, 5)

No, (3,5) is

not a solution.

If you have less than $5.00 in nickels and dimes,

find an inequality and sketch a graph to describe

how many of each coin you have.

Let n =# of nickels

Let d =# of dimes

0.05 n + 0.10 d < 5.00

or

5 n + 10 d < 500
