Question 1048608
<font face="Times New Roman" size="+2">


*[tex \Large y] must be a number of miles, and *[tex \Large x] must be a number of inches, so *[tex \Large a] must be a number of miles per inch.


We want *[tex \Large y\ =\ ax], but need to know the value of *[tex \Large a].


We are given *[tex \Large y\ =\ 75] when *[tex \Large x\ =\ 3], so we know that


*[tex \LARGE \ \ \ \ \ \ \ \ \ \ 75\ =\ 3a]


Solve for *[tex \Large a]
