1. y = 2.5        y = ?
    x = 0.25      x = 0.75

formula: y = kx (direct variation)

step 1: Find k
k = y/x
   = 2.5/0.25
   = 10

Equation: y = 10x

Step 2: Find the missing value (in this case, y)
y=10x
  =(10)(0.75)
y=7.5

2. y = 45      y = 90
    x = 3        x = ?

k = y/x
   = 45/3
   = 15

Find the missing value (x)
x = y/k
   = 90/15
x  = 6
