Answer: If your looking for the slope Intercept form, the answer is y=1x+7

You can say that the center is an arbitrary point at (x0, y0)
The distance from each point to the center is the same
d^2 = (x-x0)^2 + (y-y0)^2
Plug in each point into this equation (plug into x and y) and you have a 3x3 system that you can solve for x0 y0 which is the center and d which is the radius. Then you have the equation by putting these constants into the above equation.
It’s b. the triangles are simply just flipped
The answer is false, any number multiplied by a number lower than 1 will always decrease the original number
