Question

Help, please. Time sensitive.

What are the solutions to the system of equations?

{y=x2−3x−y=1

Solve the system by graphing.


a. (0, −3) and (0, −1)

b. (1, −2) and (−2, 1)

c. (2, 1) and (−1, −2)

d. (1, 2) and (−2, −1)

Answer 1

c. (2, 1) and (−1, −2)

Explanation:

Assuming you intended y=x²-3 and x-y=1, you can graph the parabola and the straight line (rewrite x-y=1 as y = x-1).

You can then see the intersections at x=-1, y=-2 and x=2, y=1.
