-10.35°
Add each temperature and then divide by four to find the average.
-12.1 -7.8 - 14.3 -7.2 = -41.4
-41.4 ÷ 4 = -10.35
If I am thinking right I think that the answer would be the third opption
Answer:
Step-by-step explanation:
(9 - 7)/(4 + 2) = 2/6 = 1/3 is the slope of the line
So:
Let us simply the parenthesis first.
So we have
We can rearrange the terms and get:
Which is equal to
So now we have to complete it by multiplying it all by 1/4 which is basically dividing it by 4.
So:
Simplifying that, we get:
And reducing that farther we finally get:
Which is your final answer :)
