1. The problem is to plot the point D with coordinates $\left(0, -\frac{7}{2}\right)$ on a Cartesian coordinate grid. 2. The point $D(0, -\frac{7}{2})$ means the x-coordinate is 0 and the y-coordinate is $-3.5$. 3. On the Cartesian plane, the x-axis is horizontal and the y-axis is vertical. 4. Since the x-coordinate is 0, the point lies on the y-axis. 5. The y-coordinate $-\frac{7}{2} = -3.5$ means the point is 3.5 units below the origin (0,0) on the y-axis. 6. To plot the point, start at the origin, move 0 units left or right (stay on y-axis), then move down 3.5 units. 7. The point D is exactly halfway between -3 and -4 on the y-axis at x=0, as described. Final answer: The point $D\left(0, -\frac{7}{2}\right)$ is plotted on the y-axis at $y = -3.5$.
