Best ResponseYou've already chosen the best response.0no, lets focus on squaring the parts that we found: 5, 5 would you agree that this squares to 25,25 ?

Best ResponseYou've already chosen the best response.0the formula for distance is generally stated as:\[d=\sqrt{(xx_o)^2+(yy_o)^2}\] i tend to put the wrong parts in the wrong places so I like to step thru it: subtract square add sqrt

Best ResponseYou've already chosen the best response.0given 2 point: (x,y) and (xo,yo) step1: subtract ( x, y )  (xo,yo)  xxo, yyo step2: square (xxo)^2 , (yyo)^2 step3: add (xxo)^2 + (yyo)^2 step 4: sqrt sqrt((xxo)^2 + (yyo)^2) which is how the formula is developed.
