What is the equation for the yellow line? (assume both lines are parallel)

• y=1/2x+6

• y=2x-6

• y=2x+6

• y=1/2x-6

Use slope to determine if lines AB and CD are parallel, perpendicular, or neither.

A(-3, 8), B(3, 2), C(7, 1), D(5, -1)

• Parallel

• Perpendicular

• Neither

A(3,1) B(-2,-1) written correctly is:
