Write the equation of a line in slope intercept form that is perpendicular to the line y = 3/5 x - 1 and passes through the point (-9, 4)

i belive those are the ones that are under 90 degreese.

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°
