I am going back to school after 14 + years of being out, seems as if I have lost most of my knowledge about algebra I am in need of some help solving this problem below

Graph y=5x - 2

(graphing linear equations) The sum of the squares of two numbers is 145, and the difference of their squares is 17. Which of the following pairs of equations can be used to solve this problem.

I think it is
x^2-y^2=145
x^2+y^2=17
