Lesson on Writing Equations for Parallel/Perpendicular Lines

Write the equation of a line PARALLEL to y = 2x + 3 that passes through the point (3, 1).

Write the equation of a line PERPENDICULAR to y = -2x + 1 that passes through the point (2, 3).

Select the two lines that are parallel.

• None are parallel.

What is the equation of a line parallel to the following line that passes through the given point? 
y = -4x + 6      (2, -1)

• y = 1/4x + 6
• y = -4x + 7
• y = -4x + 2
• y = 1/4x -1 

What is the equation of a line that is perpendicular to this line and goes through the given point?
y = 3x + 2      (3, -4)

• y = 3x - 2
• y = -1/3x - 5
• y = 3x - 4
• y = -1/3x - 3

Use the equations given to determine if the following lines are parallel, perpendicular, neither or both.
y=4x-2
y-3=-1/4(x-8)

• parallel
• perpendicular
• neither parallel nor perpendicular
• both parallel and perpendicular
