Question

What is the distance between points (8,3) and (8,-6) on a coordinate plane?

Answer 1

Answer: 9 units

Step-by-step explanation: if you go to K12 its correct, even though you don't have to go to K12 for it to be right it's the correct answer in general.

Answer 2

To calculate the distance between two points, we can use a formula that is a variation Pythagorean Theorem. Look:

`\mathsf{d=√((x_2-x_1)^2+(y_2-y_1)^2)}`

"d" represents the distance and coordinates are expressed as follows: (x, y)

Let's go to the calculations.

`\mathsf{d=√((x_2-x_1)^2+(y_2-y_1)^2)}\\\\ \mathsf{d=√((8-8)^2+(-6-3)^2)}\\\\ \mathsf{d=√((0)^2+(-9)^2)}\\\\ \mathsf{d=√(0+81)}\\\\ \mathsf{d=√(81)}\\\\ \underline{\mathsf{d=9}}`

The answer is 9 u.c.
