Determine whether the two lines are parallel, perpendicular, coinciding, or only intersecting. y = - 3x + 5
9x + 3y = 2

parallel

Step-by-step explanation:

if you convert the second equation it will be y=-3x+2/3, meaning they have the same slope making them parallel

answer: (c) m∠qpo + (2x + 16)° = 180°

step-by-step explanation:

the opposite angles of a quadrilateral are supplementary.

so, ∠o + ∠q = 180°   and   ∠p + ∠r = 180°

since ∠r = 2x + 16°, we can use substitution as follows:

∠p + ∠r = 180°

∠p + (2x + 16)° = 180°
