The number of miles Abigail’s boat travels, m, varies directly with the amount of time Abigail spends boating, t. If she spends 2 h in her boat, she travels 19 mi. Which direct linear variation equation models the information?
The model for direct variation is y=kx where k is a constant. In this case, y is m and x is t. So the equation is m=kt Plug in the values of m and t to find k.
