Indicate the equation of the given line in standard form.

The line containing the longer diagonal of a quadrilateral whose vertices are A (2, 2), B(-2, -2), C(1, -1), and D(6, 4).


i got -x + y + 6 = 0

Answer 1

i know the longer diagonals are B to D

Answer 2

and slope is 3/4

Answer 3

or x-y+6=0..

Answer 4

@apoorvk?

Answer 5

@dpaInc?

Answer 6

what equation did you use? your slope is right, but seems like a calculation mistake while finding the line.

Answer 7

@lgbasallote

Answer 8

y-y1=m(x-x1)
y+2=3/4(x+2)

Answer 9

4y + 8 = 4x + 2
4y + 6 = 4x
y + 6 = x

Answer 10

is that right so far? anyone??

Answer 11

your fist line, right side is incorrect...

Answer 12

in the line
4y + 8 = 4x + 2,

the right side is incorrect.

Answer 13

so the left side isnt.

Answer 14

4y + 8 is correct... i'm assuming you cleared the fraction by multiplyting the whole equation by 4.... that'll leave a 3(x+2) on the right...

Answer 15

yes

Answer 16

woops i read that wrong. okay so
4y+8=3x+2
4y+6=3x

Answer 17

the right side is still wrong .... distribute the 3 into the binomial...

Answer 18

4y+8=3x+6
4y+2=3x

Answer 19

whewww....:)
ok... proceed to make the equation in general form... make 1 side equal to zero...

Answer 20

haha sorry, silly mistakes. i'm brain fried.


4y + 2 = 3x
-3x + 4y + 2 = 0

Answer 21

that's good...
of course you know you could also write an equivalent equation in:

3x - 4y - 2 = 0

that too, would be correct...

Answer 22

:) thank you!

Answer 23

yw...:)

Answer 24

this 3x - 4y = 2 is still correct, yes?

Answer 25

yep...
