c. x1 + 3x2 = 6

Explanation:

Budget Line is the combination of goods that consumer can buy with given prices & Income (spending all).

Equation: p1. x1 + p2. x2 = m

where p1 & p2 are respective prices; q1 & q2 are respective quantities; m is the money income.

Putting p1 = 3, p2 = 9 as given:

3x1 + 9x2 = 18

Dividing the equation by common factor = 3, we get:

x1 + 3x2 = 6
