Straight lines will always add up to 180 degrees, so the angle that is missing here is supplementary to the other angle(adds up with the other angle to get 180) so we take 79 away from 180 and get 101 degrees
Brooke needs to get a 98 on the final to get an average of 80.
So you know that the total of the five given score is 382 by adding all the scores.
Now you multiply the average, 80 by 6 for the total of six tests including the final which is 480
Then you subtract 480-382 to find your answer.
Easiest way to solve this is to try plugging in the values from the table into the equations
Let’s try y = x + 4
The first coordinates from the table says
(-9 , -5 )
-5 = -9 + 4
-5 = -5
They match, so y = x + 4 is the right answer. You can try plugging in the other variables if your still uncertain
