Question

Point E is located at (2, −3), and point F is located at (−2, −1). Find the y value for the point that is the distance from point E to point F.

1.75

0.5

−2

−1.5

Answer 2

@mathmate anything?? :)

Answer 3

The distance between points E and F can be found by
\[D=\sqrt{(xe-xf)^2+(ye-yf)^2}\]
But
"Find the y value for the point that is the distance from point E to point F."
is not clear for me. Do you want to find the distance between point E and F?
y value for which point?

Answer 4

I got -2 as my answer, idk if its right. And m=i am so sorry! the blank space is 3/4

Answer 5

I am*

Answer 6

are you sure you put the question and answers in correctly?

Answer 7

Use the point of division formula.

Answer 8

yes, I put everything up correctly.

Answer 9

I chose -2 as my answer, and it was wrong...pfft

Answer 10

\[answer = -3+\frac{3}{4}(-1-(-3))\]

Answer 11

Ok, let me do that math..hold on please.

Answer 12

The correct answer is on the list of choices!

Answer 13

-1.5
lol thank you very much!

Answer 14

@mathmate one more question if you do not mind!

Answer 15

Find the x value for point F such that DF and EF form a 1:3 ratio.



0.75

−1

2

−1.75

Answer 16

so D(-3,-3), E(2,4), right?

Answer 17

DF:FE = 1:3
means that DF/DE = 1/4
are you with me?

Answer 18

Ah sorry! I totally forgot about this question. And yes I see what you are doing

Answer 19

Can you now find the point, 1/4 from D to E, using the point of division formula for each of the coordinates x and y?
Point of division formula new point P:
P(xd+(1/4)(xe-xd), yd+(1/4)(ye-yd))

Answer 20

oooo this is so confusing xO

Answer 21

@mathmate any easier way to do this? I have a test to do as well, so I am trying ot get done quick

Answer 22
