Linear Functions Review Challenge

The video tutorial covers graphing equations and inequalities using a calculator, focusing on slope-intercept form and graphing techniques. It explains how to use tables to identify patterns and calculate slopes, and delves into linear equations and their applications. The tutorial also addresses graphing inequalities and understanding their solutions, and concludes with problem-solving strategies using equations and verifying solutions.

What mode should your graphing calculator be in when graphing equations?

When graphing an inequality, what should you check about the line?

• If the line is horizontal

• If the line is solid or dashed

• If the line is dotted

• If the line is vertical

What is the first step in converting an equation to slope-intercept form?

• Divide by the coefficient of X

• Move the X term to the other side

• Add the Y term to both sides

• Multiply by the coefficient of Y

What should you always make when finding the slope of a line?
