Graphing Linear Functions by Finding X,Y Intercepts

Graphing Linear Functions by Finding X and Y Intercepts

In this video, I show how to graph a linear function by finding its x-intercept and y-intercept. This is one of the foundational techniques for graphing linear equations and can help you understand the visual representation of the function's behavior. By substituting 0 for either x or y, we can find these intercepts and plot the graph. I work through two complete examples to illustrate the process, breaking down each step for clarity. If you're new to graphing or looking for a refresher on finding intercepts, this video is for you!

What You Will Learn:

The basic concept of finding x and y intercepts of a linear function.

Step-by-step instructions on how to substitute values to find intercepts.

How to plot a linear function using its intercepts.

Visual examples that help deepen your understanding of the intercepts and their role in graphing.

10 Years after this was posted and it still is saving many lives XD

[patrickjmt]

excellent! glad i was able to help!
and do not be scared... math is hard for EVERYONE, no matter what they say : )

[Croftkid]

I love the fact that i can pause Patrick if i want to just take everything I'm looking at into perspective for a second. I can also rewind Patrick if i need to hear something again or fast forward Patrick if i already know what hes talking about. Why can't i do that in school?!?!

I'm in college and an A student, but math this semester is harder then ever. I get help from this site when it comes to math. This is a wonderful feeling! Thanks for your video's.

4 years ago I started studying for an engineering degree.. After a while I knew it wasn't for me and so I changed my direction and now I am a medical student...
One of the absolutely wonderful memories I have of that time is when I watch one of your videos and fully understand a subject I was struggling with...

Even though I didn't carry on with that direction... but I think I will always remember how amazing your explanation is...
Thank you.. I hope you are doing well

2019! you’re still saving lives . thanks 💕

I learned more from this dude in 8 minutes than my math teacher in a 30 minute zoom session

[bushcraftbrock]

you just taught something in 8 minuets that my math teacher couldn't teach me in an hour and a half. props ^^

@Glowbify well, you can add or subtract things to put it in the same form, but that is not needed. just plug in x = 0 and solve for y. plug in y=0 and then solve for x.

I'm a freshman and I'm still watching this in 2019!❤

Taking a finite math course on line. That, in and of itself, is challenging. The accompanying text doesn't provide enough examples to help grasp this. This tutorial has indeed been a great help. Thanks!

I really like how you explained it more in details ...i got a huge understanding of what you were trying say ..

[patrickjmt]

@JoanneRuth13 well, when you write the equation in y = mx + b form, that is correct

I'm a uni student and my maths subject is "Fundamentals in Mathematics" (you know, just the basics). And i have been absent in maths for 6 months before going to uni, doing nothing, and i didnt prepare. And i lost most of my knowlege on these basicsand my exam's on Monday. But when i looked through your video, it was very helpful. Man, ur teaching is much clearer than my lecturer. I hope to learn on almost evrythin i study by just watching ur vids FAST. thanks dude =)

in usa, algebra starts around grade 7 or 8 and then you use it for as long as you are taking math classes!

[marleneferguson]

THANK YOU SO MUCH!!
you helped me to get an A on my math quiz

[alianajackson]

Thanks so much. I'm a ninth grader and you are nearby the best math teacher ever. They need more like you.

[jeime]

Genius! Many have tried to teach me this, including my Algebra text book, and they all failed. I finally understand this. Thank you very much.

[patrickjmt]

@Glowbify you can use whatever method you want. did you try using this method on your example?

[luj_x]

we need more people like this i swear... my teacher gets pissed off if we ask her any question!
