Let
A( 5.0,2.8) B( -2.8,5.1)
we know that
The formula to find the distance between two points is equal to
[tex]d=\sqrt{(y2-y1)^{2} +(x2-x1)^{2}}[/tex]
substitute in the formula
[tex]d=\sqrt{(5.1-2.8)^{2} +(-2.8-5)^{2}}[/tex]
[tex]d=\sqrt{(2.3)^{2} +(-7.8)^{2}}[/tex]
[tex]d=\sqrt{66.13}[/tex]
[tex]d=8.13\ cm [/tex]
therefore
the answer is
the distance between these points is [tex]8.13\ cm[/tex]
