Understanding Perpendicular Lines

What is the first step in finding the slope of a given line?

• Subtract the y-intercept

• Rearrange the equation into slope-intercept form

• Add 4 to both sides

• Multiply both sides by 2

How do you determine the slope of a line that is perpendicular to another line?

• Use the same slope

• Double the slope

• Find the opposite reciprocal of the slope

• Subtract 1 from the slope

In the point-slope form, what do X1 and Y1 represent?

• The slope of the line

• The y-intercept of the line

• The coordinates of a point the line passes through

• The midpoint of the line

What is the purpose of distributing the slope in the point-slope form?

• To convert the equation into slope-intercept form

• To eliminate the y-intercept

• To find the x-intercept

• To simplify the slope

When using the slope-intercept form, how do you find the y-intercept of the perpendicular line?

• By doubling the x-coordinate

• By substituting the given point into the equation

• By setting the slope to zero

• By using the original line's y-intercept
