Answer: No, No, Yes, Yes, Yes

<u>Step-by-step explanation:</u>

At 2:15 the temperature is 7°

It decreases 3° every 15 minutes  ⇒ -3

Here is a table:

time  | temperature

2:15  |  7

2:30  |  7 - 3 = 4

2:45  |  7 - 3 - 3 = 1

3:00  |  7 - 3 - 3 - 3 = -2

3:15   |  7 - 3 - 3 - 3 - 3 = -5

3:30  |  7 - 3 - 3 - 3 - 3 - 3 = -8

Do you see a pattern?  This can be written as:

                                       7 + (-3) + (-3) + (-3) + (-3) + (-3) + (-3)

                                       7 - (3)(5)

                                       7 + 5(-3)
