On July 26, 2005, it rained a record 37 inches in Mumbai, India, in a 24-hour period. Which equation of direct variation relates the number of inches of rain y to the number of hours x?

Question

anonymous · Answer

direct variation means y=kx where k is a constant
if we know y is the number of inches and x is the number of hours, we can plug those into y=kx to solve for k
the equation will be 37=k*24
k=37/24
the equation will be y=(37/24)x
