Graphing Linear Functions in Standard Form

The video tutorial explains how to graph linear functions in standard form. It begins with an overview of linear equations and their different forms: slope-intercept, standard, and point-slope. The tutorial then demonstrates how to convert standard form to slope-intercept form for graphing. It introduces an alternative method using x and y intercepts for easier graphing when the C value is divisible by A and B. The cover-up method is also explained as a quick way to find intercepts. The video concludes with a summary of the methods and tips for effective graphing.

Which of the following forms is NOT a type of linear function equation?

• Point-Slope Form

• Slope-Intercept Form

• Standard Form

• Quadratic Form

In the standard form equation Ax + By = C, what must be true about A and B?

• Both A and B can be zero

• A must be zero, B can be any number

• Either A or B can be zero, but not both

• Both A and B must be non-zero

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

• Add the x-term to both sides

• Subtract the x-term from both sides

• Divide both sides by the x-term

• Multiply both sides by the y-term
