# Solving Inequalities

Chapter 2.2 - 2.3 Linear intercept -form-project.html">Equations and Slope

For each linear equation , identify the x-intercept, the y-intercept, the slope, and graph.

 Equation x-intercept y-intercept slope 1 y = 3x - 5 2 3x + 4y = 12 3 2x - 5y = 10 4

Chapter 2.7 Graphing Inequalities

Graph each inequality.

 1. y > 3x - 2 2. 3x - 2y ≥ 6 3. x < 3

Chapter 3.1 Solving Systems of Equations by Graphing

Solve each system of linear equations by graphing. Show the solution clearly .

1. y = 2x – 4
y = -3x + 1

2. x + 2y = 6
2x + y = 6

Chapter 3.2 Solving Systems of Equations Algebraically

Use elimination or substitution to solve each system of equations. Show your work.

1. 4c + 2d = 10
c + 3d = 10

2. 2x + 4y = 18
3x – 8y = -1

3. 3c = 7d - 3
2c + 6d = -34

4. Write a system of equations and solve. Be sure to define the variables used .
