Match the values in this circle to those of the standard form. The variable
r
represents the radius of the circle,
h
represents the x-offset from the origin, and
k
represents the y-offset from origin.
r
=

Answer:
x = -8.5
Step-by-step explanation:
Let's rearrange the question to find x :)

-2 -2
-2x = 17
/-2 /-2
x = -8.5
