Question 144744: I am having some trouble graphing this eqaution: y=x^2-2x-8
The question asks that I find the y and x intercepts and the vertex. I got the x intercepts at 4 and-2, the y intercept at 0,-8 and the vertex at -1,-7. The vertex doesnt seem to work though. I'd appreciate any help I could get.

Question 144893: I have a problem here that I have solved, but now I am having a problem graphing it???
I know that the intersection of the lines is (16,63), but I an not understanding how I get TWO lines??? And where to start with each line and how &/or what direction they are going, etc.?? I am lost??
x = person’s forearm
set up:
y = 4x-1 (first piece of rope)
z = 3x +15 (second piece of rope)
4x-1=3x+15
Solve for x
4x=3x+16
1x=16
x=16
Substitute
Y=4x-1
y=4(16)-1
y=64-1
y=63
z=3x+15
z=3(16)+15
z=48+15
z=63
I tried to show my graph, but it is not pasting to this section??
