(3,-8) = (x1,y1)
(-6,4)= (x2,y2)
To find the distance we have to apply the next formula:
[tex]D=\sqrt[\square]{(x2-x1)^2+(y2-y1)^2^{}}[/tex]Replace:
[tex]D=\sqrt[\square]{(-6-3)^2+(4-(-8))^2}[/tex][tex]D=\sqrt[\square]{(-9)^2+(12)^2}[/tex][tex]D=\text{ }\sqrt[]{81+144}[/tex][tex]D=\text{ }\sqrt[\square]{225}[/tex]D=15
