Question

Quick question, will give medal!

Answer 1

Please explain also, i don't understand how to do this.

Answer 2

Slope of straight line between 2 pts (x1, y1) and (x2, y2) = (y1 - y2) / (x1 - x2) okay?

Answer 3

ok

Answer 4

So u need to calculate slopes of the two lines. first for line BE, what are the coordinates of pt B and E?

Answer 5

(3,0) (4,5)

Answer 6

Very good - so can u calculate the slope for BE using the above eqn plz?

Answer 7

(3,0) and (4,5)= (3-0)/(4-5)

Answer 8

Nope read the slope eqn again plz

Answer 9

Oh sorry! (3,4) and (0,5)=(4-5)/(3-0)

Answer 10

No need to be sorry at all! u got it this time :) So what do u think the next step is?

Answer 11

Make it equal?

Answer 12

Nope there are two lines in the question right? ;)

Answer 13

Right.

Answer 14

Found the slope for that line yet?

Answer 15

No, i'm confused on how to work it out.

Answer 16

Oh sorry I thought u got it already so i was waiting for u to update. OK let's see...

The other line is AE so what are the coordinates for pt A and E?

Answer 17

(0,0) (4,5)

Answer 18

And the slope of AE is....bear w me plz - we are almost there :)

Answer 19

Idk how to find the slope, i'm confused on that.

Answer 20

Scroll up n read the slope formula again :)

Answer 21

(0,4) and (0,5)= (4-5)/(0,0)

Answer 22

Check ur eqn again....something is not right there

Answer 23

i did, it seems right?

Answer 24

i keep getting the same thing.

Answer 25

I am sorry....the two points should be A and E...

Answer 26

So the coordinates are (4,5) and (0,) sorry I didnt notice u got the wrong coordinates before.

Answer 27

ok, now what?

Answer 28

(4,5) and (0,0) so what is the slope for AE?

Answer 29

idk how to work this out though.

Answer 30

Same way u did before for the other line:

"Oh sorry! (3,4) and (0,5)=(4-5)/(3-0)"

But now the coordinates are different so u have to re-calculate

Answer 31

(0,4) and (0,5)= (4-5)/(0,0)

Answer 32

Ah there is ur problem: its NOT (0,4) and (0,5) - it should be (0,0) and (4,5)

Answer 33

(0,0) and (4,5)=(0-5)/(0,0)

Answer 34

Top part is right....check the bottom part plz

Answer 35

x1, y1) and (x2, y2) = (y1 - y2) / (x1 - x2) (0,0) and (4,5)= (4-5)/(0-0)

Answer 36

:( it should be (0-5)/(0-4)....do u understand it?

Answer 37

oh ok, i see what i did wrong,

Answer 38

OK go back to ur Q and see what they are asking? :)

Answer 39

Yes, so the slope would be 5/4?

Answer 40

Yup yup n u have to scroll ALL the way up to find the other slope that u have calculated earlier ;)

Answer 41

so the overall answer is 5/4?

Answer 42

Nope - what are the slopes for AE and BE?

Answer 43

i'm sorry, i'm confused.

Answer 44

Take ur time...go up a lil bit...we just calculate the slope of AE and it is 5/4 right?

Answer 45

yes.

Answer 46

BE is 3/1?

Answer 47

U calculated the slope of BE earlier...scroll up n find it.

Answer 48

BE is 3/1?

Answer 49

Sorry I need to scroll up n find it too....is it -1/3? Plz check savannah :)

Answer 50

i got 1,3?

Answer 51

We are looking for the slope of line BE so it is a number; not a coordinate. U have calculated it earlier. Is it -1/3?

Answer 52

Sorry, i got 1/3? not -1

Answer 53

U did this:

(3,4) and (0,5)=(4-5)/(3-0)

So is it 1/3 or -1/3?

Answer 54

i think its 1/3

Answer 55

wait no, -1/3

Answer 56

Sorry, computer crashed.

Answer 57

No prob....thought i lost u though lol

Answer 58

OK where were we? we need the slopes of lines BE and AE right?

Answer 59

Slope of BE -1/3 Slope of AE is 5/4?

Answer 60

So what is slope of BE / slope of AE?

Answer 61

i don't know what to do know.

Answer 62

now*

Answer 63

(-1/3) / (5/4)

Answer 64

Ok, how do i find the overall slope?
