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
