Question

What is the distance from (-4, -7) to (4, 8) ?

Answer 1

Answer:

17

Step-by-step explanation:

You are given two points so you use the distance formula

$\sqrt{( {x 2 - x1)}^{2} + ( {y2 - y1)}^{2} }$

Substitute your points into the formula

Answer 2

Answer:

17

Step-by-step explanation:

We can use this formula:

$\sqrt{(x2-x1)^2 + (y2 -y1)^2}$ where x and y indicate the coordinates of the two points

$\sqrt{4-(-4)^2 + (8-(-7)^2} = \sqrt{64 + 225} = \sqrt{289} = 17$
