Let's say you want to travel to Europe.  Right now, a Euro will cost you $1.263

So you can say a linear relationship exists for converting Euros into Dollars.  You'll need to decode how many Euros you want, and take the following Dollars over to exchange;

Dollars
= 1.263 * Euros

That's a simple linear relationship.

But let's say your bank charges you a fixed fee to convert your money, then you'll need

Dollars = 1.263 * Euros + Fixed_Fee

That's an example of a slope-intercept form of a linear relationship (y=mx+b)
