When would a straight-line graph be applicable in a real life situation? I can not think of any?
or could you apply this to the drinking age?
You can purchase and drink beer once you are = or greater than 21 years old?
Im I thinking on the right page?
Straight line graphs are often useful:
Mileage charts vs fuel consumption.
Number crates vs number oranges packed
and so on and so on.
