Write an equation of the horizontal line that passes through the point (4,-5).

y=-5

Step-by-step explanation:

every point on a horizontal line has the same y-value. use y-value of the point to find the horizontal-line equation.

the mean and mad

step-by-step explanation:

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°
