Re: What is the area of a triangle created by the intersections [#permalink]

Hello Asif,

Your visual representation helps big time in this instance, but your picture is very unproportional and definitely not "drawn to scale." For example, look at the difference shown between x= 0, x = 4, and x =20. That's why it's really hard to "visualize" the triangle we are trying to solve for in your diagram. The triangle should be much bigger (not small like you have pictured). The math is obviously the same, but I'm just nit picking on your drawing, sorry! lol

The one thing that I don't understand is where you got 3x + 4y = 80 from. Can you please explain? If you substitute the points they provided in the problem (x=4, y=5), you would get 32=80, which is obviously incorrect so the equation for this line does not make sense.

1st of all you have to know about patterns of gmat questions. Not drawn to scale is the format gmat uses 95%.

And here is no need to draw according to scale ,because gmat will not provide us graph paper. All we have to do is evaluate the the base and perpendicular. thats it. no one will bestow you more marks for your large drawings, you have to do fast thats it.

The one thing that I don't understand is where you got 3x + 4y = 80 from. Can you please explain? If you substitute the points they provided in the problem (x=4, y=5), you would get 32=80, which is obviously incorrect so the equation for this line does not make sense. - for this:

if three lines pass through one same point then they are unable to form a triangle. but you are insisting on that. x=4 and y=5 both values will never satisfies 3x+4y = 80, because all three lines didn't pass through one common point here.

y= -3/4 x + 20 or, 4y = -3x + 80 or, 3x+4y = 80 (got it where it came from ??? )

You need to work on basic concepts. Go through some math foundation gmat books. Any question? _________________

Thank you for the response Asif! I agree with your point that drawing to scale is not important on the GMAT exam.. but we are not in an exam center right now Hence, I thought for explaining the problem, it might have been useful to show points more accurately - similar to how I expect the OG13 answers to be shown accurately in their book's explanations. This just my preference and opinion, obviously you disagree and think it's important to "go fast" even when explaining things to others. Although, like I said earlier: not drawing to scale doesn't change anything about the question or method to solving the problem.

gmat will not provide us graph paper

They actually do give you graph "paper!" Here is a picture of the scratch pad used for the actual exam with a graph drawn for you as well (http://www.afewgoodminds.com/wp-content ... 00x150.jpg). As you stated though, I'd rather draw fast and move on quickly if I know how to solve the question.

Thanks for explaining your manipulation of the y-intercept form equation provided in the original question. Not sure why you didn't label the line with how it is stated in the original problem, but the y-intercept is supposed to 20 and it looks like the line is crossing more at y=10 (since it's about double the y=5 distance). This is why I asked.

Thank you for taking the time to respond. All the best my friend!

hmmmm right my friend..... this diagram is for concepts but not for practical uses... that's why i did so. You know one thing, the way we practice finally we have to perform just in that way.... _________________
