Question

HELP PLEASEEE!

Answer 1

Let's graph these points and connect them to get a visual of what we're dealing with here:

Answer 2

Were in the same school :P
Let me see if i can help.

Answer 3

I'm not the best at questions like this, here_to_help15 should be able to help you finish this. Use the graph if it helps. :)

Answer 4

Nice diagram. It would be helpful if the coordinates of each point is included in the diagram.

Answer 5

@Here_to_Help15 since we are in the same school you know that this is a workpad question and i have to show all of the work to get all 5 points..

Answer 6

Oh right lets see.

Answer 7

First plot the 4 points so you know how they are oriented.
Then find the slopes of opposite sides and prove they are parallel which would make it a parallelogram.
Then find the slopes of the diagonals and prove they are perpendicular. That is, the product of their slopes = -1. That will make it a rhombus.

Answer 8

I hate those questions but lemme see if i could be any help.

Answer 9

Do you think you did good with the other questions before this question?

Answer 10

This should be the last 1 or are there a couple of them?

Answer 11

this is the last one

Answer 12

A (-5,-1); B(-9, 6); C (-1, 5); D (3, -2)
What is the slope of the line AB?
Slope = \(\Large \frac{y_2-y_1}{x_2-x_1}\)

Answer 13

Sorry Reilly couldn't help:(

Answer 14

I can walk you through this question if you do the calculation part.

Answer 15

\[\frac{ -7 }{ 4 }\]

Answer 16

Good.
What is the slope of the line CD?

Answer 17

\[\frac{ -7 }{ 4 }\]

Answer 18

Good.
Slope of AB = Slope of CD = -7/4
Since their slopes are the same, AB and CD are parallel.

Answer 19

Find slope of AD.
Find slope of BC.

Answer 20

okay thank you!!!

Answer 21

\[\frac{ -1 }{ 8 }\]

Answer 22

for ad?

Answer 23

Correct.

Answer 24

\[\frac{ -1 }{ 8 }\]

Answer 25

for bc

Answer 26

Correct.

Slope of AD = Slope of BC = -1/8
Since their slopes are the same, AD and BC are parallel.

Earlier you proved AB and CD are parallel.

Since the opposite sides are parallel, this figure is a parallelogram.

Find the slope of AC.
Find the slope of BD.

Answer 27

ac= \[\frac{ 6 }{ 4 }\]

Answer 28

Yes, but simplify it to 3/2.

Answer 29

BD= \[\frac{ -8 }{ 12 }\]

Answer 30

ohh okay

Answer 31

Yes, but simplify it to -2/3

Answer 32

okay!

Answer 33

Slope of AC = 3/2
Slope of BD = -2/3

(Slope of AC) x (Slope of BD) = 3/2 x (-2/3) = -1.
If the product of the slopes is -1, the lines are perpendicular.
Therefore, AC and BD are perpendicular.

So the diagram is a parallelogram with perpendicular diagonals.
Therefore, the figure is a rhombus.
