Question

whats the distance between the points (2, -2) and (7, -8

Answer 1

Problem

whats the distance between the points (2, -2) and (7, -8​)

Solution

For this case we can use the formula for distance given by:

$d=\sqrt[]{(x_2-x_1)^2+(y_2-y_1)^2}$

And for this case x1= 2, y1= -2 , x2= 7 , y2=-8

And replacing we got:

$d=\sqrt[]{(7-2)^2+(-8+2)^2}=\sqrt[]{25+36}=\sqrt[]{61}$

And then the distance for this case would be sqrt (61) = 7.81
