Question

What is the distance of the line drawn between points (–1,–2) and (–9,4)?

Answer 1

Answer:

10

Step-by-step explanation:

( - 1, - 2 )

Let,

x1 = - 1

y1 = - 2

( - 9, 4 )

Let,

x2 = - 9

y2 = 4

Formula : -

Distance = √ [ ( x1 - x2 )² + ( y1 - y2 )² ]

Distance = √ [ ( - 1 - ( - 9 ) )² + ( - 2 - 4 )² ]

               = √ [ ( - 1 + 9 )² + ( - 6 )² ]

               = √ [ 8² + ( - 6 )² ]

               = √ [ 64 + 36 ]

               = √100

Distance = 10
