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.

***Note: WEL means Write the Equation of the Line

Pairs of Lines

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

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

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

3

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

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
