Direct Variation

✅CHECK YOUR ANSWERS✅

ON YOUR OWN ANSWERS
1) No, because the line does not pass through the origin.
2) Yes, because the y coordinate is always 4 times the x (meaning k = 4)
3) No, because the last point (1,2) does not show direct variation as the other points do.
4) No, because you can't write the equation in the form y = kx.
5) Yes, because you can write the equation in the form y = kx (y = 3x).
6) No, because you can't write the equation in the form y = kx.

This video is about how to find if two quantities (x,y) show direct variation. We are basically trying to tell if the points were to be graphed, would they pass through the origin and make a straight line. Are all points proportional with each other?

I cant tell you how thankful I am. My teachers can be a bit confusing and this helped allot

I'm in 7th grade pre algebra, i have a quiz on this tomorrow and i was absent while my class was learning this. I cant tell you how much this helped me understand direct variation. Thank you so much.

thank u so much my teacher made this really confusing, thanks

How do you do a question like: 2 + y = 4x

[aureliaeckelboom]

I know you posted this 6 years ago but I hope you know you just saved me from the stress I had about this big math test I had tomorrow.

[juliaporter]

Thank you for helping me study for my test tomorrow. Big help.
