Is this right? isn't the Directly proportional equation this. x=(1/k)y
photoshop1234 [79]
It's y=kx. But 'k' is any constant. So my 'k' can easily be 1/(your k). The key is that when 'x' or 'y' increases by some factor, the other one also increases, by some constant multiple of the same factor. If so, then they're proportional.

barxatty [35]
Hello! To solve this problem, we can write and solve an equation. Set it up like this:

6 + 3m = 24

This is because 6 is the one-time fixed price and you pay $3 per mile. Subtract 6 from both sides in order to get 3m = 18. Now, divide each side by 3 to isolate the “m”. 18/3 is 6. There. m = 6. Mike traveled 6 miles by taxi.
