Given : બિંદુ (4,-3) point (4, -3)

To Find : બિંદુ (4,-3)નું x- અક્ષથી લંબઅંતર......થાય.​

Perpendicular distance of point (4, -3) from x-axis is

Solution:

Perpendicular distance of point (4, -3) from x-axis is  

Let say point on x axis is  ( x , 0) which form a perpendicular line with point ( 4 , -3) with x - axis

Slope of x -axis is  0

Slope of perpendicular line = -1/0

Slope of Perpendicular lien =  ( - 3 - 0)/(4 - x)

= - 3/( 4  - x)  

- 3/( 4  - x)   = - 1/0

=> 4 - x  = 0  

=> x = 4

point is ( 4 , 0)

Distance from ( 4 , - 3)

= √(4 - 4)² + (-3 - 0)²

= √0² + (-3)²

= √0 + 9

= √9

= 3

Perpendicular distance of point (4, -3) from x-axis is   3
