Question

The distance between the points ( -7,1) and (-7,-1) is​

Answer 1

Answer:

mark me as brainliest

Step-by-step explanation:

$= \sqrt{ { (- 7 - ( - 7))}^{2} + {(1 - ( - 1))}^{2} }$

$= \sqrt{ {(2)}^{2} } = 2$ units

Answer 2

Answer:

2

Step-by-step explanation:

By the distance formula

distance = √(x2-x1)^2 + (y2-y1)^2

               = √(-7-(-7))^2 + (-1-1)^2

               =√(0)^2 + (-2)^2

               = √0+4

               = √4

               = 2
