Answer 2

Answer:

The parabola y = x^2 - 6x + 5 and the line y = 21 intersect at two points.

Explanation:

To find the points of intersection between the parabola and the line, we can set the equations equal to each other and solve for x:

x^2 - 6x + 5 = 21

Solving for x gives us the values of x at the points of intersection. After finding the values of x, we can substitute them back into either equation to find the corresponding y values.

The solutions for x are x = 4 and x = 0.

Therefore, the parabola y = x^2 - 6x + 5 and the line y = 21 intersect at the points (4, 21) and (0, 21).
