Choose all of the equations of vertical lines. O A. x - y = 0

B. Ox + 2y = 2

C. 3x + Oy = 7

D. 2x - y = 2

E. x + Oy = 7

F. Ox + 4y = 8

G. 12x + Oy = 24

First step is to get rid of the square root. remember that a square root is the same as raising to the (1/2) power. see below: multiply exponents per exponent rules to get: remember you subtract exponents from the denominator and add exponents in the numerator so: simplify further: so a is the correct choice. if you don't understand this google exponent rules and it will you understand. look at the image results.
