Standard & Slope-Intercept forms

What is the slope-intercept form of the equation 5x - 4y = 20?

• y = 5/4x - 5

• y = 5/4x + 5

• y = -5/4x + 5

• y = -4/5x + 5

Convert the standard form equation -3x + 6y = 12 to slope-intercept form.

• y = 1/2x + 2

• y = -1/2x - 2

• y = 1/2x - 2

• y = -1/2x + 2

If an equation is in the form Ax + By = C, where A, B, and C are constants, what is the first step to rewrite it in slope-intercept form?

• Multiply both sides by A

• Divide both sides by B

• Add A to both sides

• Subtract Ax from both sides

Which of the following is the slope-intercept form of the equation 4x + 5y = -20?

• y = -4/5x - 4

• y = 4/5x + 4

• y = -5/4x - 4

• y = -4/5x + 4

Given the standard form equation x - 3y = 9, what is the slope-intercept form?

• y = -1/3x + 3

• y = 1/3x - 3

• y = -1/3x - 3

• y = 1/3x + 3
