Answer 2

Answer: 1 unit

Explanation:

The formula for calculating the distance between two points is given as :

D =
`\sqrt{(x_(2)-x_(1)) ^(2)+(y_(2)-y_(1)) ^(2)}`

`x_(1)` = - 7

`x_(1)` = - 7

`y_(1)` = 7

`y_(2)` = 8

substituting into the formula , we have

`\sqrt{(-7-(-7))^(2)+ (8-7)^(2)}`

D =
`√(1)`

D = 1 unit
