What is the equation of a line that is perpendicular to the line y = (–1/3)x -5 and passes through the point (6, 20)

• y = 3x + 5

• y = –3x +20

• y= 3x + 38

• y = 3x +2

If lines p and q are parallel, what must be true about angles 3 and 6?

• They are complementary

• They are always equal

• They are supplementary

• They form a vertical pair

If ∠3 is 75º    and ∠6 is 75º, what can you say is true about lines m and n and why?

• Lines p and q are parallel because they never intersect because they look parallel

• Lines p and q are parallel because ∠3 and ∠6 are alternate interior angles

• Lines p and q are parallel because ∠4 and ∠6 are corresponding angles

• Lines p and q cannot be parallel because ∠3 and ∠6 do not add to 180º
