1. The problem is to plot the points A'(-2,3), B(1,-1), and C(3,-4) on a coordinate plane and understand the position of the number -8 in the bottom-right corner. 2. To plot points on a coordinate plane, we use the format $(x,y)$ where $x$ is the horizontal coordinate and $y$ is the vertical coordinate. 3. Plot point A' at $(-2,3)$: move 2 units left on the x-axis and 3 units up on the y-axis. 4. Plot point B at $(1,-1)$: move 1 unit right on the x-axis and 1 unit down on the y-axis. 5. Plot point C at $(3,-4)$: move 3 units right on the x-axis and 4 units down on the y-axis. 6. The number $-8$ in parentheses at the bottom-right corner likely represents a label or value related to the graph but is not a coordinate point. 7. The coordinate plane includes the x-axis (horizontal) and y-axis (vertical) intersecting at the origin $(0,0)$. 8. Each point is marked according to its coordinates on this plane. Final answer: Points A'(-2,3), B(1,-1), and C(3,-4) are plotted on the coordinate plane as described.
