Question

which of the following sets gives the x coordinates where the parabola y=x^2+4X-50 and the line y=7x-10 intersect when drawn in the coordinate plane

Answer 1

7x-10 = x^2 + 4 x - 50

x^2 -3x -40 = 0
(x-8)(x+5) = 0
x = 8 or x = -5
(-5,-45)
(8,46)

Answer 2

Find the coordinates of the point of intersection of the straight line y=3x_6 with the parabola y=x^2_6x+8
