The abscissa of a point refers to its x-coordinate.

For point $P(-2, 3)$:

• The abscissa is $-2$.

For point $Q(-3, 5)$:

• The abscissa is $-3$.

4. How do you find the midpoint between two points?
5. What are the differences between the abscissa and the ordinate?

Tip: The abscissa (x-coordinate) always represents horizontal movement from the origin.
