The center of circle q has coordinates (-5, -2). if circle q passes through t(-5, 8), what is the length of its diameter?

It's diameter would be 12

Step-by-step explanation:

To find the radius of the circle, you have to find the distance between two points, the difference between (-5,-2) and (-5,-8) is 6. Since diameter is twice the radius, the diameter would 12.

43

step-by-step explanation:

yes because there is exactly one y value for every x value

for function there can't be more than one value for every x value
