# Algebra: How to solve linear word problems?

I honestly don't understand how to solve linear word problems..
Here's the quesion:
1a. ) The Peanut gallery made a profit of $16,450 in 2002, and a profit of $21,340 in 2005. Assume that the profit followed a linear pattern. Write an equation that gives the profit, y, in terms of the year, x. Let x=0...

1a. ) The Peanut gallery made a profit of $16,450 in 2002, and a profit of $21,340 in 2005. Assume that the profit followed a linear pattern. Write an equation that gives the profit, y, in terms of the year, x. Let x=0 correspond to 2000.

Equation:

1b.) What was the profit in 2008

1c.) In what year would the profit be $31, 120 in the trend continued?

Please show explanations & work. I really..don't understand this.

(I obviously know the basics- solving equations, finding slope from an equation, y=mx + b, etc.)
