Exploring Key Features of Linear Functions

The video tutorial covers graphing linear functions, converting equations to slope-intercept form, identifying x-intercepts and zeroes, analyzing graphs to match equations, and finding y-intercepts using tables and linear regression.

What is the first step in converting the equation 3x + 5y = -15 to slope-intercept form?

• Subtract 3x from both sides

• Multiply both sides by 5

• Add 3x to both sides

• Divide both sides by 5
