Answer 1

i can give multiple choice if needed.

Answer 2

(3,4); (3,-4)

Answer 3

thank you

Answer 4

Do you have trouble solving this? You see both equations are equal to zero, so they are equal to each other.

x^2+y^2-25=x^2+y^2-6x-7

Solve this, by subtracting x^2 from both sides, and subtracting y^2 from both sides.
