Question
What does a linear model look like? Can you show me how to do one for math?

Answer
A linear model is where one variable is dependent on the other variable in a linear equation.
The dependent variable is y and the dependent variable is x.

The equation is then y = mx + b, where m is the multiplier and b is the constant.

For example, if they charged $10 per pizza + $20 flat rate for driving that far,
it would be y = 10x + 20.  Using this, 1 pizza would be $10 + $20 = $30, 2 pizzas would
be $10(2) + $20 = 40, 3 would be $10(3) + $20 = $50.

Now most deliveries for pizza have a closer place than that so there is no added fee.
If there were, you would most likely find a pizza place that have no mileage fee.
I only did this for the added constant.

What can I say?  That was the first thing to pop into my head ...
