Answer:
B?
Step-by-step explanation:
D
D is not a function because for every X value, there may be more than 1 corresponding Y value past 0. For instance, if you input x=1 into this function, you get both 2 and -2, which does not make this a proper function.
7 x + y = 0
x − y + 4 = 8
6 x − 3 y = 12
45 + (30*6)
