Will mark brainliest! In the system of equations below, a is a constant. For which of the following values of a does the system have no solution?

-3x + y = 6

ax + 2y = 4

I

A) -6

B) -3

C) 3

D) 6

What is the domain of the given function? {(3,-2), (6, 1), (-1, 4), (5,9), (-4, 0); o {x | x= -4,-1, 3, 5, 6} o {yl y = -2,0, 1,4,9} o {x|x = -4,-2, -1,0, 1, 3, 4, 5, 6, 9} o y y = 4,-2, -1, 0, 1, 3, 4, 5, 6, 9}
