I understood until I watched the Kahn Academy explanation and went from getting them 100% right to getting them 50% right. I watched your video for less than 3 minutes and went back to getting them 100% right. Thank you. Normally Sal from Kahn academy does a great job but his time it was a complete fail for me.

Great video Mr. Buffington Thank you! But I have a few questions: 1. I get that Y is generally always the dependent.. and like you said in the video.. "The number of hours spent looking depends on the number of golf balls found" is a nonsensical statement...But *can* it ever work or be graphed? Is there any situation or equation that allows you to solve for the independent variable (x) instead of the dependent (y) ? so basically could it ever be x = my +b? So basically, we're trying to find what the independent is, but I can't think of any situation or scientific reasoning that would need us to have the independent solved for the outcome of the dependent... 2. Can you ever have an equation... where there are no independent/dependent variables? Can both variables exist completely independent of each other? 3. if you have an equation with 3 variables....which one depends on which?? If X is still the independent, and y is the dependent, then what is Z is that equation?

Great questions! 1. You can manipulate equations to have x by itself on one side of the equation for sure. For y=mx + b, it would be an equation that looks like this: (y-b)/m = x. So while you can do it, it's not super useful. But if you are given all the y values and you need to solve for the x values, then you would probably need to set up something like this. 2. For linear equations, the points (x and y) both change as the other changes, so you can have one dependent on the other, but you can't really have two independent variables. If they were both independent that would mean basically just pick two numbers for x and y. In that case, it would be very unlikely that they would be a solution to any equation. Hope that helps. 3. When you have a linear equation with three variables, (x, y, z) you need to be given 2 to be able to solve for the third. So I guess it depends on the variables that you are given. Sorry I can't help more with that one. :)

Thanks for the speedy answer Professor! 1. So you say that if we were given all the y values we can use that to solve for the x... So basically it'd be used in situations where you are sort of "reverse engineering" something..where you have the answers , but need the input to how you got the answers? 2. So basically, if you do indeed have two variables that are completely indepedent, like in your video at the end, there wouldn't be a line, it would just be random points? Thanks for all your help and enjoy your weekend! mine will be spent studying and learning! :P

1. Yes, exactly. You could do a table of values and if you are given all the y values, you can solve for the corresponding x values. 2. A scatter plot would kinda be random x and y values put onto a graph. But for a linear equation (equation of a line) I can't think of a way to do two independent variables. :) Have a great weekend!

An equation with 3 variables would have 2 independent variables and 1 dependent. For example, the volume of a cylinder is pi times the square of the radius, multiplied by the height. The independent variables in this case would be r, the radius, and h, the height. The dependent variable is the volume V.

If there was no relationship between the variables, then it wouldn't be an equation. The values would be unrelated, and so there would be no guarantee that the left hand side and right hand side were equal.
