You do not have to be an engineer or scientist, as has been suggested, to understand and apply a linear equation(s). In fact it shows tremendous ignorance and arrogance to even suggest so:
If you make $100 per week how much will you make in a month or a year? Do you think working people do not have the sophistication to be able to come up with this linear relationship by themselves?
If I drive 150 miles on a half a tank of gas how many miles can I drive until I need more gas, and how much will it cost me if I have to drive 500 miles? Help! Call an Engineer!
If you are driving 60 miles per hour and you have to drive 500 miles how long will it take and what time will I get there if I left at 12 o'clock.
I would venture to say that cooks apply linear equations every single day in calculation of the proportions of ingredients for the food they have to prepare.

If you are an electrical engineer then linear equations are used to solve for currents and voltages in a circuit. Then you can adjust your design to make the circuit better. That's my "real life".

That depends. If you're a cook or a cleaning lady or a shoesalesperson, you won't have any use for linear equations. If you're an economist or an engineer or a scientist, you could need them every day to do your job.

It is the process of learning to think logically.
