Select the equations of the lines that are parallel to the line whose equation is y = 3x + 5.

6x + 2y = 12
-3x + y = 8
3y = 9x
y = -1/3x

Consider u = {x|x is a negative real number}which is an empty set? o {x|x eu and x has a negative cube root}o {x|x eu and x has a negative square root}{x|x eu and x is equal to the product of a positive number and -1}{x|x eu and x is equal to the sum of one negative and one positive number?
