Answer:
The method of solving "by substitution" works by solving one of the equations (you choose which one) for one of the variables (you choose which one), and then plugging this back into the other equation, "substituting" for the chosen variable and solving for the other. Then you back-solve for the first variable.

Answer:
∠8 and ∠5
Step-by-step explanation:
Vertical angles are angles that are across from each other.
∠8 and ∠5 are across from each other.
For the graph of y = -8 the line is horizontal, which means the slope = 0. A parallel line has the same slope so one equation could be y = 2. A perpendicular line has an opposite slope so since our slope = 0 the opposite of that slope is
which a line that is perpendicular to y = -8 could be x = -3. Also notice that these two lines form a 90 degree angle.
