What is a necessary step for constructing parallel lines?
draw a line that intersects the first line using a straightedge.
draw a ray that intersects the first line at a right angle using a straightedge.
draw arcs on either side of a given point on the line.
draw arcs on either side of a given point off the line.

a negative exponent is translated as follows:

so, we have

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.

i think the answer would be c
