Given:
The coordinates of the point A, (x1, y1)=(10, -5).
The coordinates of the point B, (x2, y2)=(0,-5).
The expression for the distance between points A and B is,
[tex]D=\sqrt[]{(x2-x1)^2+(y2-y1)^2}[/tex]
Substitute the values.
[tex]\begin{gathered} D=\sqrt[]{(0-10)^2+(-5-(-5)^{})^2} \\ D=\sqrt[]{10^2+0} \\ D=10 \end{gathered}[/tex]
Therefore, the distance between points A and B is 10 units.
