Step-by-step explanation:

1)

d² = (6-1)²+(3-1)²

or, d² = 5²+2²

or, d² = 25+4

so, d² = 29

so, d = 5.4 units

2)

d² = (4+2)²+(3-1)²

or, d² = 6²+2²

or, d² = 36 + 4

so, d² = 40

so, d = 6.3 units

3)

d² = (3-1)²+(-2-1)²

or, d² = 2²+(-3)²

or, d² = 4+9

or, d² = 13

so, d = 3.6 units

Answer:

1) 5.4       2) 6.3        3) 3.6

Step-by-step explanation:

Formula to find distance: [tex]d=\sqrt{(x2-x1)^{2} +(y2-y1)^{2} }[/tex]

1) coordinates = ( 1 , 1 ) , ( 6 , 3 )

   distance = √(6-1)²+(3-1)²

                  = 5.4

2) coordinates = ( -2 , 1 ) , ( 4 , 3 )

      distance   = √(4--2)²+(3-1)²

                       = 6.3

3) coordinates = ( 1 , 1 ) , ( 3 , -2 )

      distance = √(3-1)²+(-2-1)²

                      = 3.6
