PLEASE HELP
There’s a picture up!!!

(x-5)^2 + (y+4)^2 = 100

Step-by-step explanation:

The formula for the graph of a circle is . The center is (h, v). We are already given the that center is (5, -4) so we currently have .

Now we want to find the radius. We are given the center and a point that the circle passes through, so we can calculate the distance between them (which is the radius). We find that the radius is 10.

So our equation is

225x²+4=0

225x²=0-4

225x²=-4

x²=-4/225

x=±√-4/225

the answer is (-8,-5)

step-by-step explanation:

the endpoint to midpoint is half the length. the length is (-2,-1) so when you are at the midpoint just add it to it to find your answer -6+(-2)= -8 and -4+(-1)=-5 so (-8,-5)
