Quadrants in a coordinate plane start with the upper right quadrant being labeled one.
00:06
We use roman numerals.
00:07
And this is where all of your coordinates have positive x numbers and positive y numbers.
00:14
We go counterclockwise, so this will be our next quadrant, quadrant two, and this is where our x coordinates are negative and our y coordinates are positive.
00:26
And we continue counterclockwise, this is quadrant 3.
00:31
We have negative x coordinates and negative y coordinates and quadrant 4.
00:40
We have positive x coordinates but negative y coordinates.
00:46
If a point is on an x -axis or a y -axis, we do not say it's in a quadrant.
00:51
It is on an axis.
00:53
So which quadrant would you find any point? not just positive x and positive y.
01:00
If we were looking for the product of the x and y coordinate to be greater than zero, so that means we need a positive product great, not equal zero, but greater than zero.
01:14
So we are looking for the multiplication of x times y must be positive...
