A (3, 5) B (-2, -2)

Distance between AB = √(x₂ - x₁)² + (y₂ - y₁)²= √(-2-3)² + (-2-5)²= √(-5)² + (-7)²= √25 + 49= √74.

Find the distance between A(3,5) and B(-2,-2)

Pick one of the points to be point 1 and the other to be point 2. It doesn't matter which you pick as point 1.

But, it is important that you keep the same order when you plug coordinates into the Distance Formula.

I choose point B to be point 1 ... B(-2₁,-2₁)

and point 2 to be A ... A(3₂,5₂)

So,

D = √[ ( 3-(-2) )²   + ( 5-(-2) )² ]

D = √[ ( 3+2 )²   + ( 5+2 )² ]

D = √[ 5²   + 7² ]

D = √[ 25   + 49 ]\

D = √( 74 )            ← ANSWER

Use the distance formula to determine the distance between the two points.  Distance  =  √  (  x  2  −  x  1  )  2  +  (  y  2  −  y  1  )  2

Distance=(x2-x1)2+(y2-y1)2

Substitute the actual values of the points into the distance formula.  √  (  1  −  3  )  2  +  (  3  −  (  −  5  )  )  2  (1-3)2+(3-(-5))2

Simplify.    Tap for more steps...  2  √  17  217

The result can be shown in multiple forms.  Exact Form:  2  √  17  217  Decimal Form:  8.24621125  …  8.24621125…          (  3  ,  −  5  )  (  1  ,  3  )  (3,-5)(1,3)
