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
