Let's say Cost(x) = 2x + 3 dollars
----------------
slope is 2 and intercept = 3
----------
Intercept:
That equation says: even if you buy zero items, the base cost is $3
When the independent variable is zero, the dependent variable value is the intercept.
--------------------
Slope:
That equation says: for each item bought, the cost rises $2.
The slope is ALWAYS the amount the dependent variable increases
when the independent variable increases by one.
