distance formula is like pythagoren ahtoerem
D=[tex] \sqrt{(7-2)^{2}+(5-8)^{2}} [/tex]
the distance between oints (x1,y1) and (x2,y2) is
D=[tex] \sqrt{(x1-x2)^{2}+(y1-y2)^{2}} [/tex]
A=(-3,-1) and (5,2)
D=[tex] \sqrt{(-3-5)^{2}+(-1-2)^{2}} [/tex]
D=[tex] \sqrt{(-8)^{2}+(-3)^{2}} [/tex]
D=[tex] \sqrt{64+9} [/tex]
D=[tex] \sqrt{73} [/tex]
aprox
