Question

What is the distance between the points (8, -3) and (1,5) ?

Answer 1

`d=√(113)`

Explanation:

`(8, -3)= (x_1,y_1)\\(1,5) =(x_2,y_2) \\\\d = √(\left(x_2-x_1\right)^2+\left(y_2-y_1\right)^2)\\\\d = √(\left(1-8\right)^2+\left(5-\left(-3\right)\right)^2)\\\\d = √((1-8)^2 +(5+3)^2) \\\\d = √((-7)^2+(8)^2)\\ \\d = √(49+64)\\ \\d = √(113)`
