To find the distance of line \( D \), you typically need more information such as the coordinates of two points that lie on the line or the equation of the line itself.
The distance between two points in a 2D space can be calculated using the distance formula:
\[ d = \sqrt{(x_2 - x_1)^2 + (y_2 - y_1)^2} \]
Where \((x_1, y_1)\) and \((x_2, y_2)\) are the coordinates of the two points.
If you have the equation of the line in the form \( Ax + By + C = 0 \) and you want to find the distance from a point \((x_0, y_0)\) to the line, you can use the formula:
\[ d = \frac{|Ax_0 + By_0 + C|}{\sqrt{A^2 + B^2}} \]
Please provide the necessary information so I can help you calculate the distance to the nearest tenth.
