Answer:
   y = 18
Step-by-step explanation:
Direct variation means y will change by the same factor x does. When x changes by a factor of 15/10 = 1.5, the value of y will change by that same factor
   x = 10, y = 12
   x= 15, y = 1.5×12 = 18
The new value of y is y = 18.
_____
Written as a proportion, you have ...
   y/15 = 12/10
   y = 15×12/10 = 18
__
Written as a direct variation equation, you have ...
   y = kx
   12 = k·10   ⇒   k = 1.2
   y = 1.2·15 = 18 . . . . for x=15
