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)
