1.) What is the equation given a slope of ½ and a y-intercept of 4? 2.) What is the slope of an equation y=2x-5

3.) What is the y-intercept of an equation y=7x+8?​

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°
