The slope of two parallel lines: ​ (a)  

• m1 = m2

• m1 = -(1/m2)

• m2 = -(1/m1)

Sadie graphed the equations y = 4 and y = -7. These lines are ​ (a)   and their slopes equal ​ (b)   .

• parallel

• perpendicular

• opposites

• zero

• undefined

Mabel graphed the equations y = (1/3)x + 2 and y = 3x + 2.

These lines are​ ​ (a)   because their slopes are ​ (b)   .

• perpendicular

• intersecting at an angle that is not 90 degrees

• parallel

• reciprocals, but are not opposites

• equal

• opposites, but not reciprocals
