Opener:

Work on the 4 Warm-up Problems individually during announcements. After announcements, you will have a few minutes to work with your partner. If you are stuck on any of them, use your textbook, but FIRST try each one to the best of your ability.

Writing the Equation of a Perpendicular Bisector:

Pairs of Lines

y = 5x + 8y = 5x - 4

y = 2x -5y = 4x + 3

y = -3x - 6y = x + 51_

3

y = 2x - 4y = 2x - 4

13

Classifying Pairs of Lines:

Match each set of lines to the corresponding type of pair of lines.y = 2x + 3 and y = 2x -1

y = 3x -5 and 6x - 2y = 10

3x + 2y = 7 and 3y = 4x + 7

3x + 5y = 2 and 3x + 6 = - 5y

y = 3x - 6 and 18y = -6x +36Parallel Lines
