Question

.If A(x1,y1) and B(x2,y2) are two points on a straight line AB parallel to X-axis then ..​

Answer 1

Answer:

answer is |x2-x1|

Step-by-step-explanation.

Given:

AB is parallel to the x - axis.

When AB is parallel to the x - axis, the y co - ordinate of A and B will be the same.

i.e., y1 = y2

Distance =  √ ( x 2 − x 1 ) 2 + ( y 1 + y 1 ) 2 (x2−x1)2+(y1+y1)2 ⇒ |x2 – x1| Therefore the distance between A and B when AB is parallel to x - axis is |x2 – x1|
