THANK YOU FOR ADDING VALUE TO THE INTERNET WITH YOUR VIDEOS.

Professor RobBob, thank you for Showing and Modeling Word Problems with Linear Functions Part One. These real life word problems only helps the general public makes good financial choices. Cars and Houses are the two largest purchases that people make everyday on planet earth.

ProfRobBob....Thanks for all your hard work you put into these vidoes. I am currently studying for the math portion of the teaching state test, which I have failed three prior times, and your videos explain in a way I can understand. I go to an online school for my teaching degree so I have no profs. I can go too. Bless you and Thanks again.

Not a huge fan of word problems. But, I still appreciate the help. Thank you for the help!

Thanks Mr. algebra has been hard for me and this helped me.

Your a great teacher I wish you were my teacher

[TKMe]

Funny, understandable, nice and fun class I loved it. Love your handwriting too.

[Shivxngee]

This is truly fantastic. Thank you so much. 😊

can you do a video on this i dont understand it and all your other videos help graphing system of linear inequalities word problem

[elanelle]

Amazing! btw, what is the importance of this linear function model?

[erwinjedracho]

Sir rob. i think u should use "greater than or equal to" sign if ur going to use the word "at least".

The line you used to connect the points implies that selling half a car would give you a $100 commission and overall $1100 pay. Instead, what would be a more appropriate means to connecting the points?

[horizonbrave]

BAM! So if this were a slope intercept form equation... The 1000 dollars would be the "b" correct? Meaninging that the 1000 is the y intercept? So what's the main difference between this function and just using the slope intercept form?

Plot Twist: The guy at the door was RobBOb's clone and taught the rest of the math video

Please do a video on penmanship; I love the beautiful and readable cursive. By the way, the videos educational content was very good. Thanks for the Video.

My math teacher made me watch this Help me Bhs

[julissadelgado]

Im in 8th grade and still confused about linear functions

[lilymae]

Okay but why would you say you can't buy a half of a car? As a sales man I would think the car was magically sold at half price. 🤣

Please don't use cursive. Many people can't read it.
