How to plot points A(2, 5), E(2, 1), B(4, 0), and F(-2, -1) on a Cartesian coordinate plane, and determine their locations?

The task is to describe how to plot the given points on a Cartesian coordinate plane. For each point $(x, y)$, we start at the origin $(0, 0)$, move $x$ units horizontally (right if $x > 0$, left if $x < 0$), and then $y$ units vertically (up if $y > 0$, down if $y < 0$).

To plot $A(2, 5)$:

• Start at the origin $(0, 0)$.
• Move 2 units to the right along the x-axis.
• From there, move 5 units up parallel to the y-axis. The point $A(2, 5)$ is located in the $\boxed{\text{First Quadrant}}$.

To plot $E(2, 1)$:

• Start at the origin $(0, 0)$.
• Move 2 units to the right along the x-axis.
• From there, move 1 unit up parallel to the y-axis. The point $E(2, 1)$ is located in the $\boxed{\text{First Quadrant}}$.

To plot $B(4, 0)$:

• Start at the origin $(0, 0)$.
• Move 4 units to the right along the x-axis.
• Since the y-coordinate is 0, the point lies on the x-axis. The point $B(4, 0)$ is located on the $\boxed{\text{Positive x-axis}}$.

To plot $F(-2, -1)$:

• Start at the origin $(0, 0)$.
• Move 2 units to the left along the x-axis.
• From there, move 1 unit down parallel to the y-axis. The point $F(-2, -1)$ is located in the $\boxed{\text{Third Quadrant}}$.
