Question

graph the linear equation 2x = 6. tell whether it represents a function.

i don't understand how you would solve the equation. where does y do?

Answer 1

it is a vertical line, the line \(x=3\)
a vertical line fails the vertical line test miserably, it is not a function

Answer 2

thanks! i'm taking this quiz online, and it showed a graph with a vertical line, and it said, that "yes," it was a function.

Answer 3

i got confused, thanks!!
