Use horizontal and/or vertical translations to choose the correct equation for each line described below.

1. A line with slope 3, passing through point $(13,9)\text{.}$
   Answer: $y =$ ? 3(x-13)+9 13(x-9)+3 9(x-13)+3
2. A line passing through point $(13,15)$ with slope 9.
   Answer: $y =$ ? 13(x-15)+9 13(x-9)+15 9(x-13)+15
