Find an equation of the parabola with focus (-1, 1) and directrix x = -5.

When the solutions to each of the two equations below are graphed in the xy-coordinate plane, the graphs of the solutions intersect at two places. write the y-cordninates of the points of intersection in the boxes below in order from smallest to largest. y=2x y=x^2-3

What are the solutions of the system? solve by graphing. y = -x^2 -6x - 7 y = 2

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
