I am unsure what 7-√ is, so I will assume the radius is 7. Since we know the equation of a circle is (x-h)^2+(y-k)^2=r^2 with h and k being the x and y coordinates of the circle respectively, we can then plug in the radius and other variables to our utmost ability, and solve it for fun.

Answer:y=x-4 and y=x+10

x=y+4 and x=y-10

Step-by-step explanation:I am unsure what 7-√ is, so I will assume the radius is 7. Since we know the equation of a circle is (x-h)^2+(y-k)^2=r^2 with h and k being the x and y coordinates of the circle respectively, we can then plug in the radius and other variables to our utmost ability, and solve it for fun.

(x-10)^2+(y+13)^2=49

x-10+y+13=+-7

Case 1:

x-10+y+13=7

y=x-4

x=y+4

Case 2:

x-10+y+13=-7

y=x+10

x=y-10
