Question

Find the length of the diameter with endpoints of (1,-3) and (5,-6) *

Answer 1

5

Explanation:

if the point A is (1;-3), the point B is (5;-6), then

1. the formula of the required length is:

`d=√((X_A-X_B)^2+(Y_A-Y_B)^2);`

2, after the substitution of the coordinates of the points A and B into the formula of the required diameter:

`d=√((1-5)^2+(-3+6)^2)=√(16+9)=5.`
