Best ResponseYou've already chosen the best response.0Ignoring the idea of regions, would you know how to graph 2x5y = 0 as a line?

Best ResponseYou've already chosen the best response.0No.. I could if zero was another number. I have no examples for this kind of problem

Best ResponseYou've already chosen the best response.0The fact that the other number is 0 actually just means that you have a yintersect of 0. Are you familiar with slopeintercept form?

Best ResponseYou've already chosen the best response.0Alright. So if I were to put your inequality into slopeintercept form I would have: \(2x  5y \ge\ 0\) \(2x \ge\ 5y\) \(\frac{2}{5}x \ge\ y\) So that it maybe looks in a better order, let's rewrite this as \(y \le\ \frac{2}{5}x\) Now, you know slopeintercept form is \(y = mx+b\) where m is the slope and b is the yintercept. So here we have a slope of 2/5, but no value for b. This means that the yintercept is 0. So with that information, we can graph this line. Would you be able to graph it given the info above?

Best ResponseYou've already chosen the best response.0Graph just the line I mean, don't worry about the region part yet.

Best ResponseYou've already chosen the best response.0Just making sure :) Well, if we start from the yintercept of 0 and use a slope of 2/5, we can get this line: dw:1433634764962:dw So how the line is drawn makes sense?

Best ResponseYou've already chosen the best response.0Okay, so now the region part. So when the inequality says \(y \le\ \frac{2}{5}x\), it's saying that the correct yvalues must be less than or equal to the line. As in the region we want are all the yvalues on the line and under the line, meaning we would have this: dw:1433634956029:dw So basically, once you put a line into slopeintercept form, if you have \(y \le\) , you're graphing everything under the line and if you have \(y \ge\), you're graphing everything above the line.

Best ResponseYou've already chosen the best response.0I dont see how. This is the plot of the graph http://www.wolframalpha.com/input/?i=2x5y+%3E%3D0 @Destinyyyy

Best ResponseYou've already chosen the best response.0The correct answer is how I graphed it above. The slope is 2/5, so every point is up 2 and right 5 from the previous point. The way you graphed the line in the screenshot is with a slope of 5/2. But I gave the correct graph.

Best ResponseYou've already chosen the best response.0The first graph is the correct answer the second is my answer (what you gave me).

Best ResponseYou've already chosen the best response.0Right, and that first graph is what I gave you. I'm not sure where you're seeing that my graph is the graph on the right of your screenshot. dw:1433636211206:dw Those are the points on my graph and the points on the graph marked as correct on your screenshot.

Best ResponseYou've already chosen the best response.0I see. I don't mind being wrong and corrected when I am wrong, but as long as you get the correct answer and understand it, then that's what matters. Sorry if there was any confusion.
