- Write the points whose ordinate is 0.
- Write the points whose abscissa is –5.

उत्तर
- We know that, the point whose abscissa is 0 will lie on Y-axis. So, the required points whose abscissa is 0 are A, L and O.
- We know that, the point whose ordinate is 0 will lie on X-axis. So, the required points, whose ordinate is 0 are G, I and O.
- Here, abscissa –5 is negative, which shows that point with abscissa –5 will lie in II and III quadrants. So, the required points whose abscissa is –5, are D and H.
Notes
We know that, origin O is the intersection point of both axes. So, we can consider it on X-axis as well as on Y-axis.
