Hi, I’m Krista! I make math courses to keep you from banging your head against the wall. ;)

Math class was always so frustrating for me. I’d go to a class, spend hours on homework, and three days later have an “Ah-ha!” moment about how the problems worked that could have slashed my homework time in half. I’d think, “WHY didn’t my teacher just tell me this in the first place?!”

every other video on this topic stops when they realize the lines are parallel. thank you for showing what to do for EVERY option, instead of designing a problem that is done at step 1 then stopping at step 1.

This woman is saving lives here. I'm so grateful for your videos, they are so clear and thorough.

Ah, I love how you showed us every possibility, and explained every single step. Even though some steps were not necessary to explain, you did it anyways & that just solidifies our understanding. Thank you so much.

This video is organized!!!! I loved it. Thank you very much. I loved the "if not, then" strusture you used

[Malik-jthi]

You’re literally a goddess, THANK YOU. I’m straight up boutta fail calc 3 but maybe a little less because of you

Just discovered you 3 hours before my exam, wow I wouldn't have written anything if it wasn't for you

Nicely covered and thanks for going over examples on each case.

I just came from a patrickJMT video on the same topic and yours helped so much more, not sure if I paid more attention since I still couldn't get it or you just explained all possible outcomes instead of just for that specific problem. Thank you so much you just saved my calc final :)

I am just amazed that how you simplify these topics and make them easy for us👍😀

[hazzah]

Omg thank u so much, i read other articles on how to find perpendicular lines and they said that you have to make sure the lines intersect first. I was so confused until I came across ur video. Thanks

[danieltorres]

If I could like this video a thousand times I would! Thanks Krista!

You're not uploading videos, you're saving some people's lives

[modestmii]

Thank you for this. We never went over this class or on the assignments and yet, teacher says we have to know this for this test tomorrow :P

[adelasiri]

I feel so confidence when I watch your vids, I know that I will understand the problem at the end.

[eddyuceta]

great videos, awesome quality, clear explenations. love it

[bahaatamer]

here's what happens in my maths lectures: Go to class and know what topic to revise (honestly, our teacher's voice is hard to follow up with). Soon, I arrive home, open YouTube and search for your videos and start understanding what the heck was going on... You made my life much easier tbh! Thanks a ton once again Krista, and I am definitely going to continue learning from you, PatrickJMT and Khan Academy :D

[ashw]

Exactly what I wanted... Tks Krista <3

[jeffersonhuynh]

Your examples are crystal clear. Thank you so much, Krista!

Amazing video. Totally helped me with math class cuz i had to skip a few class due to family business. Now I get to finish homework lolz

[Kalo]

Thanks a lot! If we had a teacher like you we wouldn't be raging at theory. :(
