Plot Points B28B3A

1. To plot points on a coordinate plane, you need to understand the directions: up, down, left, and right. 2. The horizontal axis is called the $x$-axis. Moving right means increasing the $x$-value, and moving left means decreasing the $x$-value. 3. The vertical axis is called the $y$-axis. Moving up means increasing the $y$-value, and moving down means decreasing the $y$-value. 4. For example, to plot the point $(3, 2)$, start at the origin $(0,0)$, move 3 units to the right (because $x=3$), then move 2 units up (because $y=2$). 5. Similarly, to plot $(-2, -4)$, start at the origin, move 2 units left (because $x=-2$), then move 4 units down (because $y=-4$). 6. Remember: right and up are positive directions, left and down are negative directions on the coordinate plane.
