Answer 1

Write an equation of each circle:

Answer 2

This is an eyeball problem. Just write it down. It really is that simple.

Answer 3

Is it \[(x + 7)^{2} + (y - 3)^{2} = (6)^{2}\]

Answer 4

or is the -3 supposed to be just 3?

Answer 5

You're turned around.

Center at x = 7 leads to (x-7)
Center at y = -3 leads to (y+3)

ohhh ok thanks!

Answer 7

The next one will be an eyeball answer, right? :-)

Answer 8

yeah haha. But i have one more question, what if it says the same thing at the beginning but then for the 2nd part it says and passes through (1, -1)?

Answer 10

Providing Center, Radius AND a point on the Circle? Too much information. Center and radius completely define the circle. It's only luck if you hit the point.
