Question

use the points on the coordinate plane to find the distance dc.

Explanation:

Step1: Determine the coordinates of points D and C

Assume each grid is 1 unit. Let's find coordinates. If we consider the standard coordinate system (from the look of the grid - usually origin at lower - left, but since it's not specified, we count the vertical and horizontal steps).
Suppose point \(D=(x_1,y_1)\) and point \(C=(x_2,y_2)\). Counting the vertical units (up - down direction). If we assume the vertical distance: count the number of grids between D and C.
Counting from D to C: move 5 units up (assuming the vertical axis).

Answer:

The distance \(DC = 5\) units.
