Someone answer urgent and if so I will mark brainliest

B) (x,y) -> (-x,y)

Step-by-step explanation:

By reflecting across the y axis, all y values stay the same, therefore no matter what happens to the x, the second half will be y -> y

Because of the reflection across the y axis, you are simply taking all x values and multiplying by -1 to get x -> -x.

Thus, (x,y) -> (-x,y)

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.
