Predict the value of y for x = 60. How do I do this?

You could do this with an equation which it might be asking so I it could be like

3 times x = 60

or 30 times x = 60

The value of y will stretch into infinity and negative infinity. This is due to the fact that the line must always stay on the value of x = 60, therefore creating a vertical line on a graph that will result in an infinite amount of values of y.
