Question

What is the distance between the points (7, 8) and (-8, 0) on a coordinate grid?

Answer 1

Answer:

17 units

Step-by-step explanation:

Use the distance formula, $d = \sqrt{(x_2 - x_1)^2 + (y_2-y_1)^2}$

Plug in the points and simplify:

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

$d = \sqrt{(-8 - 7)^2 + (0-8)^2}$

$d = \sqrt{(-15)^2 + (-8)^2}$

$d = \sqrt{225 + 64$

$d = \sqrt{289$

$d = 17$

So, the distance between the points is 17 units
