I don't think so. Would the answer be all of them?If x is 10 can you give me a y such that y = x? If so thats the point (10,y)
If x is 12.3 can you give me a y such that y = x? If so thats the point (12.3,y)
If x is any value can you give me a y such that y = x? If so thats the point (x,y)
Do you see the solution now?
An "S" shape is plotted. The points above the graph are symmetrical to the points on the bottom. The only point that is labeled is (1,1). The very center of the "S" is at (0,0).I'm sorry, I didn't see that there was an attachment. I thought your question was a bit easier. Your attachment awaits approval, can you describe it for me?
Yes, at (0,0)You've certainly got me confused! What lines did you draw at (1,1), (2,2), etc.?
I have no idea what you are talking about when you say "At 0, there are 3"! What do you mean "at 0"? Do you mean "at (0,0)" or "at x= 0" or "at y=0"? And there are 3 what?
The problem is asking "where does this graph cross the line y= x?" That's difficult to answer here because it depends strongly on how accurate this graph is supposed to be and exactly where each end of the "S" ends. Can you draw the line y= x?
The line y = x consists of all the points where *drumroll...* y = x. For example, (0, 0), (1, 1), (2.439, 2.439), etc. Plot two of these points on the graph (maybe (0, 0) and (1, 1) ). The straight line that connects these points is y = x. It extends out infinitely past both points.Yes, at (0,0)
I don't understand what you mean by the line y=x. I don't know where to draw it, or how/why it's just one line.
I am sorry to confuse you. Things get lost in translation in this format.
I'm not getting the concept but I am trying hard.
I sort of understand that. But I still don't understand what the answer is.The line y = x consists of all the points where *drumroll...* y = x. For example, (0, 0), (1, 1), (2.439, 2.439), etc. Plot two of these points on the graph (maybe (0, 0) and (1, 1) ). The straight line that connects these points is y = x. It extends out infinitely past both points.
The number of points on the line y = x is infinite, but the number of points where the line y = x intersects your "S" is not. Draw the line y = x as well as the "S," and the points where the lines cross will be the intersection points.I sort of understand that. But I still don't understand what the answer is.
How many are there? It seems that the number is infinite.
3?The number of points on the line y = x is infinite, but the number of points where the line y = x intersects your "S" is not. Draw the line y = x as well as the "S," and the points where the lines cross will be the intersection points.
For example, in http://education.yahoo.com/homework_help/math_help/solutionimages/minialg2gt/12/1/1/minialg2gt_12_1_1_27_110/f-438-1-we-1.gif", there are two points where the line intersects the ellipse.
I came up with 2.y=x is a straight line, at an elevation of 45 degrees from the x-axis, working counterclockwise. Plot that, and the answer will be however many times that graph and the line intersect.
Would you believe on a wing and a prayer?Good! How did you come up with that? I presume you have a clearer picture than we can see on the internet, because I was not at all sure. (Of course, I didn't want to draw on my computer screen!) Obviously, as you said, (0,0) is one point of intersection. Is the other in the lower left (3rd quadrant) or upper right (1st quadrant)?
It's all I have. It might have been easier had the graph been better.If you look at the graph (the image has finally been approved), you will see that the origin and also the two end points of the S all lie on the line y = x, so there are actually 3 points that the line y = x intersects. The end points of that graph should really be labeled, though.
