Question

The distance between the points (-7,8) and (-16, 8

Answer 1

Solution :-

Let the two points be A and B

The coordinates of point A = ( -7 , 8 )

The coordinates of point B = ( -16 / 8 )

Now,

We have to find the distance between A and B

Therefore,

By using distance formula,

$XY \: = \: \sqrt{ {(x2 - x1)}^{2} + {(y2 - y1)}^{2} }$

Here, x1 = -7 , x2 = -16

y1 = 8 , y2 = 8

Subsitute the required values :-

$AB \: = \: \sqrt{ {( - 16 -(- 7 )\: )}^{2} \: + {(8 - 8)}^{2} } \\ AB \: = \: \sqrt{ {( - 9)}^{2} + {(0)}^{2} } \\ AB \: = \: 81$

Hence, The distance between A and B is 81 units .
