Given the following system of equations and their graph below, what can be determined about the slopes and y-intercepts of the system of equations? A line includes points 0 comma 1 and 2 comma negative 4. A line includes points negative 1 comma negative 7 and 0 comma negative 6.
5x + 2y = 2
3x − 3y = 18

if you need just tell me and i will come to the rescue.

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°
