    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
