Question

Find the distance between the points (-3,- 2.2) and (-3,2.6).

Plz explain I want to see if I got it right.​

Answer 1

d = 4.8 units

Explanation:

(
`x_(1)` ,
`y_(1)` )

(
`x_(2)` ,
`y_(2)` )

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

~~~~~~~~~~~

( - 3, 2.6 )

( - 3, - 2.2 )

d =
`√((-3+3)^2 +(-2.2-2.6)^2 )` = √(- 4.8)² = 4.8 units
