Parallel and Perpendicular Lines Graphically

Write an equation that is parallel to 
y = -2x + 4
and runs through the point (-3, 2 )

• y = - 2x - 4

• y = - 2x - 8

• y = - 2x + 4

Are these lines parallel, perpendicular, or just intersecting (but not perpendicular)?

• Parallel

• Perpendicular

• Intersecting (but not perpendicular)

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)

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)

write the equation of a line that is parallel to y = -7x + 5 and passes through the point (0, 6)

• y = -7x + 6

• y + 0 = -7(x - 6)

• y = 6

• y + 6 = -7(x - 0)

y = 5/7x +2
y = 5/7x - 30
These lines are...

• Parallel

• Perpendicular

• Neither
