Answer:
For #1 a real life problem that could use this information would be "If a mud wall is built 24 feet high, and rain reduces the height by 6 feet every year, how long will it take the wall to disappear altogether?".
Step-by-step explanation:
When designing a problem like this when we already know the answer, use the y-intercept as a starting point. In this case, we start with a 24 foot wall.
Next use the rate as what changes for every unit. In this case, the height changes every year by -6.
Finally, the answer should always be the x-intercept.
