Chapter 3: Coordinate Geometry

Questions

1. Where does $(0, -4)$ lie?
2. Plot $(2, 3)$ and $(-2, 3)$; observation?
3. Distance of $(7, 24)$ from origin.
4. A point on $x$-axis at distance $5$ from origin.
5. Both coordinates negative — which quadrant?
6. Distance between $(1, 2)$ and $(4, 6)$.
7. Reflection of $(3, -4)$ across origin.
8. Coordinates of a point $4$ units below the $x$-axis and on the $y$-axis.
9. Which axis does $(5, 0)$ lie on?
10. Perpendicular distance of $(-3, 4)$ from the $x$-axis.

Extra Practice (Optional)

• Plot $(3, -2), (-1, -1), (0, 4)$.
• Find the point equidistant from both axes in Q-I with distance $3$.
• Distance of $(-6, 8)$ from origin.
• Reflection of $(-5, 2)$ across the $x$-axis.
• Coordinates of the origin.
