You need to come up with an array of answers for x and y that will be greater than 0.
x+4y>0. example if x is -1 and y is 1 will this be correct.
-1+(4*1)>0, -1+4>0. 3>0? Yes
if x is 1 and y is -1 then the equation becomes 1+(-4)>0 -3 is not>0 so it's not in the array
x could be -3 and y 1
You will plot a line to show all the answers.

Answer:
The average price of a ticket originating in Chicago using United Airlines is $1212.40.
Step-by-step explanation:
The data provided is as follows:
United Air France British
Chicago 1063 1314 1442
1299 1493 1413
995 1443 1063
1299 1577 1442
1406 1314 1575
London 1015 1374 1603
856 977 1531
802 1043 1079
850 1070 807
935 1428 870
The data for the price of a ticket originating in Chicago using United Airlines is:
Chicago = {1063, 1299, 995, 1299, 1406}
Compute the average price as follows:

![=\frac{1}{5}\times [1063+1299+995+1299+1406]\\\\=\frac{6062}{5}\\\\=1212.40](https://tex.z-dn.net/?f=%3D%5Cfrac%7B1%7D%7B5%7D%5Ctimes%20%5B1063%2B1299%2B995%2B1299%2B1406%5D%5C%5C%5C%5C%3D%5Cfrac%7B6062%7D%7B5%7D%5C%5C%5C%5C%3D1212.40)
Thus, the average price of a ticket originating in Chicago using United Airlines is $1212.40.
X equals five plus or minus the square root of negative five squared minus four times two times eighteen, all divided by two times two
