She should multiply y = x - 2 by -4...that way one x will be -4x and the other will be 4x and they will cancel out when added.
answer is -4
The discriminant of this equation is 49. The solutions for this equation are x=2 and x=-

I hope that helps.
Step-by-step explanation:
y= x +2
.is the equation of line pass through B, C
I dont get what you’re asking ?
