Find the distance between the points A(3,-3) & B (7,-5)​

Answer»

Step-by-step explanation:

distance = \sqrt{(x2 - x1)^{2} + {(<klux>Y2</klux> - y1)}^{2} }

Here (x1, y1)=(3,-3) and (x2, y2)=(7,-5)

USING the formula,

distance = \sqrt{ {(7 - 3)}^{2} + {( - 5 - ( - 3))}^{2} }

distance = \sqrt{4^{2} + ( - 2)^{2} }

distance = \sqrt{16 + 4} = \sqrt{20}

distance = 2 \sqrt{5} units
