Question

Find the distance between the two points (0,9) (-8,-4) 233 9.4 15.3 21

Answer 1

Answer: third option.

Step-by-step explanation:

You need to use the formula for calculate the distance between two points:

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

Given the points (0,9) (-8,-4), you can subsitutute each coordinate into the formula  $d=\sqrt{(x_2-x_1)^2+(y_2-y_1)^2}$ to calculate the distance between them.

Then, you get that the distance between these points is:

$d=\sqrt{(-8-0)^2+(-4-9)^2}\\d=\sqrt{(-8)^2+(-13)^2}\\d=15.3$

This matches with the third option.
