The mean or better known as the average is all of the numbers combined and then divided by how many numbers there were. You should be able to find the mean of any set of numbers. There might be a mistake in the calculations some where.
Answer:
-12 / 17
Step-by-step explanation:
x | -1 | 2 | 5 | 8 |
-----------------------
y | 3 | -1 | -5 | -9 |
Piking the poits at the extreme:
x1 = - 1 ; y1 = 3
x2 = 8 ; y2 = - 9
Slope = Rise / Run
Rise = y2 - y1 = - 9 - 3 = - 12
Run = x2 - x1 = 8 - (-9) = 8 + 9 = 17
Hence,
Slope = - 12 / 17
Take the values given for domain which is the x-axis and plug then in for x to get your range which is the y-axis value
Answer:
