Question

Find the distance between the pair of points (2,-5) and (3,-7).

Answer 1

2.24

Explanation:

`d=√((x_2-x_1)^2+(y_2-y_1)^2)\\\\(2,-5)\quad\implies\quad x_1=2\,,\ \ y_1=-5\\\\(3,-7)\quad\implies\quad x_2=3\,,\ \ y_2=-7\\\\d=√((3-2)^2+(-7+5)^2)= √(1^2+(-2)^2)=√(1+4)=\sqrt5=2.236....\approx2.24`
