Question

The distance between the two parallel lines L1: −7 x − 10 y=−4, L2: −7 x − 10 y=3 is
???

Answer 1

its not 7 i've tried that

Answer 2

its not 7/10 or .7 either

Answer 3

1

Answer 4

i got to 7 myself and tried it on the answers it said its wrong

Answer 5

Its not, graph it!

Answer 6

And then measure it yourself :-D.

Answer 7

its not 1 either

Answer 8

What do the answers say?

Answer 9

when i punch it in says its incorrect

Answer 10

Sooory

Answer 11

its 0.7!

Answer 12

Because \[ -7x-10y=c \] gives you \[y=-7/10 x - c/10 \]
Plug in -4 and 3 and you get 4/10 as opposed to -3/10.

Answer 13

And 4/10 - (-3/10) = 7/10 = 0.7

Answer 14

the answer is 7/10
since
we have
-7x-10y=-4=> y=-7x/10+4/10
-7x-10y=3=> y=-7x/10-3/10
so they have a distance of 4/10-(-3/10)=7/10 from each other

Answer 15

it says its incorrect :"(

Answer 16

But it is not incorrect. That is the right answer, we just proved it.

Answer 17

Your answer sheet is flawed.

Answer 18

did you write down the right equations

Answer 19

yeah copy paste the same exact thing

Answer 20

−7 x − 10 y=−4
−7 x − 10 y=3
