Yes, the YouTube videos from 2006 are really helping!

[zoeh]

You taught me a weeks worth of material in 10 minutes

[minrose]

5:07 y equal or less than 6 so you have to use solid line. 😀 Thanks.

[GabrielTobing]

Hey dude, thank you so much, this was literally the last question on one of my assignments, and I did it easily because I watched this video a few days ago. Thank you so much man, you've really helped me to understand maths a lot.

I hope you always get a nice cold pillow <3

[abigroenewold]

Just letting you know that in the third problem u need to make y less than or equal to 6, a solid line

[sallylally]

Math exam tomorrow or I guess later today since it's 1 am

MR. Organic Chemistry Tutor, thank you for a solid demonstration of Graphing Systems of Linear Inequalities. I did not fully understand this material in Precalculus, when I took the class in the 1980's at the old Catonsville Community College in Baltimore County, Maryland.

[Darksparklight]

Anyone else study before the state math test that’s literally tomorrow because you didn’t pay attention in class?



No just me?

[zetriac]

Mr. Organic Chemistry Tutor, I love you bro your lessons are always hit when needed.

[matthewrodrigo]

Personally i think it would have been better just to substitute iether y or x with a number to get atleast 2 coordinates. In that way it saves time

[rxs]

I. think the gray line should not be dashed

[readyunboxing]

5:07 y equal or less than 6 so you have to use solid line. 😀 Thanks.

[bri-_-]

Thank you so much your videos are really helpful. I do not know what I would do without them. They have taught me so much material when I had struggled. I appreciate it!

[yiningliu]

greater and equal to 6 for the 4:23 question, supposed to be solid line NOT dashed line.

[karthikeyanbreakless]

Vendantu and byjus is nothing in front of u bro

[joshuapujante]

Thanks as always you've been my guide from junior high school up until now that I am in college you're still my guide especially I'm not that good in math. A big thanks for you from me :3

[burhanyounis]

There is a problem at 4:40. The second inequality, y<=6, was graphed with a dashed line instead of a solid line.

[samimesfin]

I got A at math and physics after watching your videos thanks brother keep up you really help

[pricilacamille]

On the second problem he made a mistake y is less than or equal to 6 was supposed to be solid he put it dash.

[nahidch]

When do we use solid line or opposite?
