Determine if the graph is a function

• no it does not pass the vertical line test

• yes, every output has a unique input

• no it's not a straight line

• yes because it goes from negative to positive

• no because it does not go thru quadrant 2

• y = -4x + 1

• y = 4x -1

• y = -2x + 3

• y = 2x - 5

• y = 3x - 6
