Find the slope of A. The slope of a line parallel to A would have the same slope of A. Remember, slope=rise over run.
X => -8 -6 -8 3
y => 33 31 39 33
is not a function because the x value -8 results to two different y-values 33 and 39.
Answer:
The temperature of the solution after 3 hours rounded to the nearest whole degree is -6 C
Step-by-step explanation:
From the question, the temperature of the chemical solution at the start of the experiment is -14.96 C.
Now, if the temperature increases by 2.9 C each hour,
Then, after 3 hours, the temperature of the chemical solution would have increased by
2.9 C/h × 3 h
8.7 C
Hence, the temperature of the chemical solution would have increased by 8.7 C after 3 hours.
The temperature of the chemical solution after 3 hours will be
-14.96 C + 8.7 C
= -6.26 C
≅ -6 C (to the nearest whole degree)
True, because dot plots usually look like this
0 0
0 0 0 0 0
