think about linear relationships and when you might see them in real life. explain a time when you see linear relationships and when they will be useful!

A few real-life examples are:

- Buying multiple of the same item.

- Figuring out how long a car will take to cover a certain distance when traveling at a fixed speed.

- Starting with a certain amount of money and spending a certain amount of it each day.

Step-by-step explanation:

Buying multiple of the same item.

In this case, the linear function would look like this:

Total = 0 + (Cost of the item x Number of the item)

This would be useful for trying to figure out your total!

- Figuring out how long a car will take to cover a certain distance when traveling at a fixed speed.

Say that a car was traveling at 60 miles per hour and needed to drive 200 miles but you didn't know how long it would take. You could use this equation  to help figure it out:

Distance (200 miles) = 0 + (60 x Hours)

- Starting with a certain amount of money and spending a certain amount of it each day.

If you had $200 and planned to spend $5 a day, how many days would you be able to spend money? In this case, we need to figure out when our balance will reach 0.

0 = 200 - ($5 x Number of Days)

~Hope this Helps!~
