Problem 89 of 7
After substituting the line into the parabola, classify intersections using the discriminant for x^2-x-2=0.
Using a hint is okay. It just tells the trainer to give you a little more review.

1. Identify a, b, and c in the substituted quadratic.
2. Compute b^2-4ac.
3. Use the sign of the discriminant to classify the number of real intersections.
Use the worked steps, then substitute the final answer back into the original relationship to confirm it satisfies the prompt.
Classifying negative discriminant as no solutions without specifying no real intersections for the graph.
