Parallel and Perpendicular Functions

What is the equation of the parallel to the line shown and passing through the point (1,-1)?

What is the equation of a line that passes through (-2, -5) and is parallel to y=x+3

• y = x - 3

• y = x + 5

• y = -x - 3

• y = -x + 5

Write the equation of a line perpendicular to y = 3x - 8 and that passes through the point (-3, -9)

• y + 9 = -1/3(x + 3)

• y - 9 = -1/3(x - 3)

• y + 9 = -3(x + 3)

• y - 9 = 3(x - 3)

Perpendicular lines have ________ slopes

• -1/4

• -4

• 1/4

What slope is perpendicular to:  
m = 3

• -3

• -1/3

• 1/3

• 3

y = -2/3x + 2
y = 3/2x + 9
These lines are...

• Parallel

• Perpendicular

• Neither

Choose ALL the lines PARALLEL to the following line: y = 2/9x - 7

• y = 2/9x + 8

• y = 9/2x -12

• -2y = 9x + 8

• 9y = 2x -18

Select ALL of the lines that are PERPENDICULAR to y = 3/4x + 9

• y = 3/4x - 3

• y = -3/4x + 9

• y = -4/3x + 8

• 3y = -4x + 5

• 4y = -3x + 7

Write the equation of a line parallel to y = -1/2x + 3 and that goes through the point (4, -1)

• y + 1 = -1/2(x - 4)

• y - 1 = -1/2(x + 4)

• y + 1 = 2(x - 4)

• y - 1 = 2(x + 4)
