The graph of y= -2x+ 10 is: A. a point that shows one solution to the equation.

B. a point that shows the yintercept.

C. a line that shows the set of all solutions to the equation.

D. a line that shows only one solution to the equation.

what is the answer

Evaluate the discriminant of each equation. tell how many solutions each equation has and whether the solutions are real or imaginary. x^2 - 4x - 5 = 0
