Answer 1

graph each equation at www.desmos.com/calculator
if they are the same line the pair has many solutios
if they intersect at one point it is C
if they don't intersect at all it is A
if they intersect at two points, it is D

Answer 2

I can already say that it isn't D though because none of the variables have exponents
