Asock drawer contains 10 white socks, 6 black socks , and 8 blue socks if 2 socks are chosen at random, what is the probability of getting a pair of white socks?

How to solve it and what thw answer is

Solve by any method (graphing, substitution or linear combination)y = x - 82x + 3y = 1a) (2, -6)b) (5, -3)c) (4, -4)d) (0, -8)i figured it out. the answer is (5, -3)

Find the equation of the line with slope =8 and passing through (6,53) write your equation in the form y=mx+b
