22. the graphs of the lines y = - 2x-3,
y= 1/2x + 2, and y = 1/7x + 24/7 are shown
below. the three lines intersect to form the
right triangle abc.

How do i do this activity, is appreciated

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

Can someone answer this question for me
