Understanding Parallel Lines and Slope-Intercept Form

What is the slope of a line that is parallel to another line with a slope of 1/4?

• 1/2

• 2/4

• 1/4

• 4/1

Which form of the equation is used to find the equation of a line given a point and a slope?

• Quadratic form

• Point-slope form

• Slope-intercept form

• Standard form

What operation is necessary to eliminate the parentheses in the point-slope form equation?

• Addition

• Subtraction

• Multiplication

• Division

How do you isolate the y-variable in the slope-intercept form?

• Add the x-variable to both sides

• Subtract the x-variable from both sides

• Add or subtract constants to both sides

• Multiply both sides by the slope

What is the final form of the equation after converting from point-slope to slope-intercept form?

• y - y1 = m(x - x1)

• x = my + b

• ax + by = c

• y = mx + b
