Notice that for each ordered pair in the graph, the y-value is 16 more than the x-value.
Which of the given ordered pairs has a y-value that is not 16 more than its x-value?

B.? @mathstudent55

Correct, since it's the only ordered pair that you add something other than 16 to x to get y.
7 + 15 = 22
15 is not 16.
