Question
Find the distance between the following pair of points
(3, −9) and (−2, 3)
Advertisements
Solution
Distance between the two points (3, −9) and (−2, 3)
= `sqrt((x_2 - x_1)^2 + (y_2 - y_1)^2`
= `sqrt((-2 - 3)^2 + (3 + 9)^2`
= `sqrt((-5)^2 + (12)^2`
= `sqrt(25 + 144)`
= `sqrt(169)`
= 13 units
