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

Direct variations have lines passing through the origin (0,0).
If the line passes through (10,60), the slope is 60/10=6.
That should help you to choose the right answer.
