Answer: See below
Step-by-step explanation:
a. The ordered pairs (0, -6) and (0, -11) have in common they have the same value on the X-axis.
This means the to point while on diferrent height are one upon the other on the plain, which mean they create a line that is perpendicular to the Y-axis and totaly perpendicular to the X-axis.
b. To calculate the distance between two points on a 2-d space, we can use the following equation:
Distance (D) = [tex]\sqrt{(x_{1}-x_{2} )^{2} +(y_{1}-y_{2})^{2} }[/tex]
Where the ordered pair [tex](x_{1}, y_{1} )[/tex] defines one point and [tex](x_{2}, y_{2} )[/tex] defines the other.
D = [tex]\sqrt{(0-0 )^{2} +(-6+11)^{2} }[/tex]
D = 5
The distance between the two points [tex](x_{1}, y_{1} )[/tex] and [tex](x_{2}, y_{2} )[/tex] is 5
