Question

What is the exact distance from (-5,1) to (3,0)

square root of 69 units

square root of 65 units

square root of 63 units

square root of 50 units

Answer 1

Using Pythagoras theorem, we have

Exact distance = square root(8^2 + 1^2) = square root (65).

Answer 2

So then it would be B, right?

Answer 3

yes

Answer 4

thanks!

Answer 5

The distance, \(d\), between points \((x_1, y_1) \) and \((x_2, y_2) \) is

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

This is called the distance formula and it comes from the Pythagorean theorem.
