The diagram shows parallel lines p, q, and r cut by transversal t. match each angle pair to the correct description.

1 is to a because corresponding angles are located in the same location, comparative to each line.

2 is to d because one, they are on the same side of the transversal, and two, they are "facing" each other.

3 is to c because vertical angles are formed opposite to each other when two lines intersect, like shown.

4 is to b because they are on different sides of the transversal, and are "facing" each other.

5 is to e because they are not "facing" each other, and they are on different sides of the transversal.

check above link.

graphically?   well, you graph them both, the solutions is where they both intersect each other, since there are two solutions, meaning they will meet twice, or namely the linear will run into the quadratic curve twice, and where they meet, those x,y coordinates are the solutions to the system.
