The vertices of JKL are J(-1,4) K(2,-5) and L(2,2) the triangle is reflected over the line y = x Graph JKL and J’K’L

Can someone me and do the problem plz so i can understand it more better

The lengths of two sides of a right triangle are given. find the length of the third side. round to the nearest tenth if necessary. a) y = 12/5x + 39/5 b) y = 5/12x + 5/39 c) y = 12/5x - 39/5 d) y = 5/12x - 5/39

Which statement about the annual percentage rate (apr) is not true?
