Question

Write the direct variation equation for the following: y varies directly with x and y = 60 when x = 10.
A. y = 1/6 x
B. y = -1/6 x
C. y = 6x
D. y = -6x

Answer 1

y= 60
x=10
y=6(10)=6x

Answer 2

When you hear y "varies directly with" x, you should make a ratio: y to x, or y:x, or y/x. I prefer to write them as fractions for this question.

60 to 10 or 60/10
Reduce: 60/10 = 6/1 = 6
The answer is 6.
