Answer 2

If the co-ordinates of the points are of the same sign, then the points lie in the quadrants I and III

Step-by-step explanation:

In order to find where the points of the same sign lie in a graph, let's first assume a set of coordinates we wish to mark.

The only condition given here is that both x and y co-ordinates should be of the same sign, meaning both are positive or both are negative.  

Let's take x co-ordinates 2 , 4, -3, -5. Then Y co ordinates can be 1, 3, -2, -7 (assumption).

We chose random numbers here, just making sure that the co-ordinates have same sign.

So if we plot a graph and join the co-ordinates (2, 1), (4, 3), (-3, -2) and (-5, -7), it will pass through the quadrant I and quadrant III.

Please refer to the picture to know where the quadrants lie.
