Answer:
Option D
Step-by-step explanation:
Distance between two points
The y-value of the two points is unchanged. So, the line is parralel to x-axis.
The distance will be the diffrence between the x-co ordinates.
[tex]\sf Distance = 1 - (-2\dfrac{1}{2})[/tex]
[tex]\sf =1+\dfrac{5}{2}\\\\= \dfrac{2}{2}+\dfrac{5}{2}\\\\=\dfrac{7}{2}\\\\=3\dfrac{1}{2}[/tex]
