We just might have a problem... that you'll understand...we all need shmoop...

00:11

Which equation contains the point (1, 10)?

00:13

And here are the potential answers...

00:18

OK so to find the equation that contains the point (1, 10)...

00:21

...we basically just have to plug in x as "1" into all of the answer choices to

00:26

see which one is on the line of the actual equation.

00:36

Here we go... hold on to your... plugs...

00:50

2 times 1 squared plus 3 times 1 plus 2...

00:54

equals 2 plus 3 plus 2, or 7. And a 7, sadly... is not a 10.

01:04

1 squared plus 4 times 1 plus 3... equals 1 plus 4 plus 3, which equals 8... so we're

01:11

still lookin' for the princess who fits the shoe.

01:17

3 times 1 squared plus 4 times 1 plus 4... equals 3 plus 4 plus 4... or 11.

01:25

10 isn't even greater than 11, so that doesn't work.

01:30

On to D... 2 times 1 squared plus 5 times 1 plus 3... equals 2 plus 5 plus 3... or 10.

01:38

Bingo! D should be our answer! Just to check E... 2 times 1 squared plus 5

01:43

times 1 plus 6... equals 2 plus 5 plus 6...or 13. Nope.

01:48

D it is.

01:50

Okay -- you can let go of your plugs now.
