A circle is graphed on a coordinate grid and then reflected across the y axis. if the center of the original circle was located at (x, y), which ordered pair represents the center of the new circle after the transformation?

(-x,y)

Step-by-step explanation:

If it's positive and you flip it accross the y-axis, the x- coordinates become negative.

-7

step-by-step explanation:

x^2 + 18x + 74 = (x + 9)^2 - 81 + 74

= (x + 9)^2 - 7.

so q = -7.
