It is the line of symmetry of a parabola and divides a parabola into two equal halves that are reflections of each other about the line of symmetry.
Answer: x = -2 and 4
Step-by-step explanation:
x^2 - 2x - 8 = 0
(x - 4)(x + 2) = 0
I’m not sure what you’re options are but an equation in Y=mx+b form for this would be y= -3/2x + 5
M is always the slope
B is always the y intercept
