Question

PLEASE HELP WILL MEDAL AND FAN

A grid shows the positions of a subway stop and your house. The subway stop is located at (7, -6) and your house is located at (-9, 5). What is the distance, to the nearest unit, between your house and the subway stop?

Answer 1

The quickest solution is to find the horizontal distance, then the vertical distance, then use the Pythagorean theorem to solve.\[distance = \sqrt{x ^{2} + y ^{2}}\]

Answer 2

I've been doing that, but I'm not getting the correct answer @mjdennis

Answer 3

Show me. What is the distance from "your house" to the subway in the x-direction?

Answer 4

-9,5

Answer 5

19
29
21
24
those are my answer choices. I think it's C but I'm not sure

Answer 6

(-9,5 is not a distance, it is an x,y position.)

Answer 7

Sorry, not solving it for you. I'll show you how to do the work, though.

First, what is the _x_ _position_ of your house?

Answer 8

I don't want you to solve it for me, I need help. I don't get it, that's all.

Answer 9

Every position on the grid is known my two numbers called coordinates. The horizontal numbers are "x" coordinate and the vertical numbers are "y" coordinates. Wwe write the numbers we always write the x-coordinate first. So (1, 2) means go one unit across-right and two units up. (-3,-1) means go 3 units left and 1 unit down.

What is the (x,y) position of your house?
What is the x-position?
What is the y-position?

Answer 10

okay I'm pretty sure it's 19

Answer 11

Once again, based on the fact you are not showing me any intermediate steps, I am not giving any answers.

If you want my continued help, please follow the steps so I know what you are doing:
What is the (x,y) position of your house?
What is the x-position?
What is the y-position?

Answer 12

Okay according to my grid, If I got down to the negatives which is 9 and across 5 I land on 6

Answer 13

Your house is at (-9, 5). Those numbers are LEFT/RIGHT first, then UP/DOWN, not the way you described.

Maybe you better attach this "grid", because there seem to be extra numbers involved.

Answer 14

okay. I was going down instead of up. That was my mistake

Answer 15

For -7, 6 I do the same thing correct?

Answer 16

-6*

Answer 17

You also mixed up which one comes first. Always, always, always across, then down.

Answer 18

Okay. I'll do the same thing for the other

Answer 19

okay that's 6, -7 right?

Answer 20

No, those labels on the grid are just labels. They only measure distance if you are going along the line. Ignore them for the rest of the problem.

The (x,y) position of your house is (-9,5), just like it says in the problem description
The x-position is -9
The y-position is +5

Does that make sense?

Using that way of reading numbers, answer the following:

What is the (x,y) position of your subway stop?
What is the x-position?
What is the y-position?

Answer 21

Okay -9 + 5 = -4
7 + -6 = 1

Answer 22

+7 = 7 left,
-6 = 6 down

Are you checking what you are doing before you type?

Answer 23

Sorry, I'm not good at math.. I'll try to figure it out myself. Thanks for your help, though
