Describe how to place a point in the coordinates axes. Then say what the horizontal and vertical axes are called.
See development and solution
Development:
Theoretical exercise.
Solution:
To place a point $$P=(a, b)$$ in the plane, the procedure to follow is the following one:
- We draw a coordinates axes.
- We place point $$a$$ in the horizontal axis and point $$b$$ in the vertical axis.
- We draw straight lines perpendicular to the axes for $$a$$ and for $$b$$.
- The intersection of the previous perpendicular lines is point $$P$$.
The horizontal axis is called the abscissa axis. The vertical axis is called the ordinates axis.
