Here's your shmoop du jour.

00:04

Which ordered pair is not on the line shown?

00:08

And here are your options...

00:12

OK so it's one of those "NOT" questions. Which means we have to go through each answer

00:17

choice to figure out which one of those ordered pairs is NOT on the line...(0,1).

00:22

Yup the line intersects the y-axis

00:25

at (0,1). (-4, -2)...yeah... the line intersects that

00:29

point in the bottom left-hand quadrant of the coordinate plane.

00:32

(-4, -1)...wait didn't we just have the x coordinate of -4 correspond with the y-coordinate

00:38

of negative 2?

00:41

The definition of functions tells us that that every input has one and only one output.

00:46

So if (-4,-2) is on the line... (-4,-1) can't be. Looks like our answer has to be C.

00:54

But just to be sure...(4,5) is on the line in the upper right hand corner here...

00:58

Last choice...(2, 2.5). The graph doesn't

01:02

have perfect tick marks...but it looks close enough...definitely more accurate than (-4,-1).

01:07

So our answer is indeed C.
