Converting Linear Equations to Slope-Intercept Form

What is the formula for slope-intercept form?

• y = mx + b

• x = by + m

• y = bx + m

• x = my + b

How do you convert an equation to slope-intercept form?

• Divide each term by the y-intercept

• Isolate y on one side

• Multiply each term by the slope

• Isolate x on one side

How do you eliminate the 4x term from the equation 4x + 2y = -8?

• Divide both sides by 4

• Add 4x to both sides

• Multiply both sides by 4

• Subtract 4x from both sides

What is the slope of Line A after conversion?

• 4

• -4

• 2

• -2

In the equation y = -2x - 4, what does -4 represent?

• The coefficient of x

• The y-intercept

• The x-intercept

• The slope

Why can't the equation 4x = -8 be converted into slope-intercept form?

• Because it's already in slope-intercept form

• Because it represents a horizontal line

• Because it doesn't have a slope

• Because it doesn't have a y variable

What does the equation x = -2 represent on a graph?

• A horizontal line through -2

• A vertical line through -2

• A diagonal line with slope -2

• A diagonal line with slope 2

What is the slope of Line B?

• -2

• Undefined

• 0

• 2

What is the y-intercept of Line C?

• -2

• -4

• 4

• 0

What does a slope of 0 indicate about a line's graph?

• The line is vertical

• The line is horizontal

• The line is increasing

• The line is decreasing
