Answer:
equation is x = -9
Step-by-step explanation:
There is no slope its a vertical line
A^2+b^2= c^2
48^2+b^2= 80^2
2304+b^2= 6400
Subtract 2304 from both sides.
b^2= 4096
Find the square root.
b= 64
I hope this helps!

C = the square root of a^2 + b^2
AC = the sqrt of AB^2 + BC^2
AC = sqrt of 6^2 + 10^2
AC = 11.66
Answer:
G
Step-by-step explanation:
vertex formula = a(x-h)^2 + k
vertex is (h, k) so (-1, -4) means
y = a(x+1)^2-4
passes through (1, 8) so when x = 1 and y = 8
8 = a(1+1)^2-4 = 4a - 4
4a = 4
a = 1
