Graphing Linear Inequalities in Standard Form

The video tutorial covers graphing inequalities in standard form, focusing on solving for Y and graphing the resulting lines. It explains the process of moving terms, dividing by coefficients, and handling inequalities with greater than or less than signs. The tutorial also addresses the importance of dashed and solid lines based on inequality symbols and demonstrates how to shade the solution area. Special attention is given to flipping inequality signs when dividing by negative numbers.

What is the first step in solving for y in the inequality 4y + 2x = 8?

• Divide by 4

• Subtract 2x from both sides

• Multiply by 4

• Add 2x to both sides

After moving the x term in the inequality 4y > 2x + 8, what is the next step?

• Multiply by 4

• Divide by 4

• Subtract 2x from both sides

• Add 2x to both sides

When graphing the inequality y > -1/2x + 2, what type of line should be drawn?

• Bold line

• Dashed line

• Solid line

• Dotted line
