10-127.

Solve algebraically to find all points where the graphs of y = x2 − 3x + 2 and y = 2x + 8 intersect. Homework Help ✎

Use the Equal Values Method. Note that since you have an x2-term, you should be looking for two answers.

Substitute your answers, one at a time, back into one of the equations, and solve for the corresponding y-coordinates.

(−1, 6) and (6, 20)
