name the quadrant in which the following the points lie: i(1,1) ii(2,4) iii(-3,10) iv(-2,1) v(5,-1)
any one knows the answer
Do you know what the quadrants are?
its written in the Q?
I meant in general. They start in the upper right with 1 and go counter clockwise. |dw:1411407173154:dw|
yeah in know this
i will send the question wait
OK. So if you look at those, you can generalize the positive and negative: |dw:1411407372596:dw|
ok
So, anything with a positive x value will be in quad 1 or 4. If the y is also postitive, it will be in 1. If the y is negative, it will be in 4. You can evaluate each of the points that way.
x axis is the positive side and y axis ins the negative side
No. Both have positive and negative +X is Right of the origin -X is Left of the origin +Y is Above of the origin -Y is Below of the origin
So by looking at the + or - of both the x and y value you can say, "This is right/left and above/below the origin, therefor in quad..."
what does both have possitive and negative mean
You said, "x axis is the positive side and y axis ins the negative side" I was not sure what you meant, so I went back to general, which is there can be both + and - x values on the entire x axis and + or - y values on the entire y axis. Are you talking about quad 4? That would be a (+x,-y). Anything with a positive x and negative y is quad 4.
yeah quad 4
OK. Yes, that is what q4 would be.
So if you look at the 5 points you listed, one of them is in Q4. The others are not.
thanku so much because i have exam tommorow
