Question

Find the difference between each of the following pair of points - (2,-11) (-9,-3)
With explanation please​

Answer 1

Answer:

given,

co-ordinates of :-

P = ( 2 , -11 )

let,

2 = x_1

-11 = y_1

Q = ( -9 , -3 )

let,

-9 = x_2

-3 = y_2

to find : -

distance between the two points.

formula used : -

$d = \sqrt{(x_2 - x_1)^{2} + (y_2 - y_1)^{2} }$

$\huge\sf\underline{solution}$

d = √ (-9-2)² + (-3-(-11))²

= √(-11)² + (-3+11)²

= √121+(9)²

= √121+81

= √202 units
