<h3><u>Answer:</u></h3>
- My little brother will have to wait for 12.5 minutes to drink his hot chocolate.
We know that in 5 minutes, the temperature of the hot chocolate decreased by 10 degrees. We also know that the temperature is fixed at 70 degrees. Now, using the info given, let's solve!
- => 5 minutes = 10 degrees decrease
- => 1 minute = 2 degrees decrease
- => 1 minute x 12.5 = 2 x 12.5 degrees decrease
- => 12.5 minutes = 25 degrees decrease
Therefore, my little brother will have to wait for 12.5 minutes to drink his hot chocolate.

Step-by-step explanation:
A line segment has 2 end points which can be denoted as:
and
When this line segment intersects at y.
This means that the coordinate on the y axis is the same at both end points
i.e.
and
becomes
and
x1 and x2 can be any value but the y value must remain unchanged
Using the above analysis, a possible coordinate is:
and
Note that there are as many answers as possible as long as the coordinate pair satisfy is of the form <em> and </em>
