Answer:4 units

Step-by-step explanation:Distance formula:

[tex] \sqrt{(x1 – x2)^{2} + (y1 – y2)^{2} } [/tex]

[tex]length \: of \: line \: xy \\ = \sqrt{(3 – 3 )^{2} + (1 – ( – 3))^{2} } \\ = \sqrt{(1 + 3)^{2} } \\ \ = \sqrt{4^{2} } \\ = 4 \: units[/tex]

Or since both coordinates lie at x=3, the line is a vertical line so you can simply count the increase in y to find the distance of the line.

1-(-3)= 4 units
