What form is the equation 3x - 4y = 24 in?

• Exponential form

• Slope-intercept form

• Quadratic form

• Standard form

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

• Divide both sides by the x-term

• Add the x-term to both sides

• Subtract the x-term from both sides

• Multiply both sides by the y-term
