a parking meter gives 30 minutes for each quarter and 6 minutes for each nickel. the equation 30x+6y=60 describes the number of quarters x and nickels y that you need to park for 60 minutes what does the xintercept represent?

From the coefficients of the equation, you would have to figure out that x represents the number of quarters, and y=number of nickels.
The xintercept means the number of quarters required if y=0 (no nickels used.)
