Question

find the difference between (3,2) and (11,8) in Co ordinate geometry ​

Answer 1

Heya

______________________________

Difference between two points in co-ordinate geometry mean distance between two given points.

P1 = ( x1 , y1 )

And

p2 = ( x2 , y2 )

Then their Difference/Distance is given by

d = √{(x2 - x1)² + ( y2 - y1)² }

Here x1 = 3 , y1 = 2 , x2 = 11 and y2 = 8

=>

d = √{11 -3 )² + ( 8 - 2)²}

=>

d = √{64 + 36 }

=>

d = √(10)²

=>

d = 10

OR

d = -10

d = -10 will be rejected becoz distance can't be -ive

So, Difference/Distance between two given points is 10units
