Question

What’s the distance between the points (7,3) and (7,-8)

Answer 1

Answer:

Displacement = 11 units.

Step-by-step explanation:

The displacement(shortest distance) between two points can be calculated by:

d = √((x1-x2)²+(y1-y2)²) . --(i)

Having,

'd' as displacement.

'x1,y1' as the co-ordinates of starting point.

'x2,y2' as the co-ordinates of the ending point.

Now, as we are given two points, let 'P1' and 'P2' be the two points respectively; thus,

P1(x1,y1) = (7,3).

P2(x2,y2) = (7,-8).

Now, for the shortest distance, simply put the points in the above mentioned formula (i):

d = √((7-8)² + (3-(-8))²)

d = √(0² + 11²)

d = √(11²)

d = 11 units.
