Using the equation y = 3x - 5, what would the output be for an input of - 4?

your question is really not clear but if you were to put the - 4 in the Y then the answer would be X=1/3, if you plug in - 4 for X and find Y then Y = - 17

Step-by-step explanation:

plug in - 4 in Y

-4=3x-5 add 5 on both sides,

1 = 3x divide 3 on both sides

1/3 = x

plug in - 4 in X

y = 3 (-4) - 5 multiply 3 and - 4 = - 12

y = - 12-5 subtract the - 12 and - 5 = - 17

y = - 17
