Question

What is the distance between (1,-5) and (-3,6)​

Answer 1

`\large\boxed{√(137)\approx11.7}`

Explanation:

The formula of a distance between two points:

`d=√((x_2-x_1)^2+(y_2-y_1)^2)`

We have two points (1, -5) and (-3, 6). substitute:

`d=√((-3-1)^2+(6-(-5))^2)=√((-4)^2+11^2)=√(16+121)=√(137)`
