Answer 1

???

Answer 2

\[y = \frac{ -3x }{ 4 } + 3\]
\[y-3= \frac{ -3x }{ 4 }\]
\[4(y-3)=-3x\]
\[4y-12=-3x\]
\[3x+4y=12\]

Answer 3

?

Answer 4

in what part are u confused?

Answer 5

Is that for question 16?

Answer 6

yes

Answer 7

Theres not "+" in the options though

Answer 8

Did you mean division?

Answer 9

that's addition right there in the image isn't it.

Answer 10

nope i dont think so :P

Answer 11

yep it is addition lol
download the image and zoom it.. you'll see. :D

Answer 12

O ok lol

Answer 13

Can you do 17 and 18 please?

Answer 14

okay but did u understand how to get the answer? :)

Answer 15

To be honest, no. xD

Answer 16

\[y=\frac{ -2x }{ 3 } + 2\]
subtracting 2 to both sides (so 2 at the right will be canceled)
\[y-2=\frac{ -2x }{ 3 }\]
multiply 3 to both side (so 3 at the right will be canceled)
\[3(y-2)=-2x\]
\[3y-6=-2x\]
now, standard form is --> x+y=z where z is constant ye?
the final answer must be
\[2x+3y=6\]
make sense?

Answer 17

Yeah helps. thanks

Answer 18

i think you can do the last question ?

Answer 19

Answer 24

for the first one it is perpendicular because the slope of the first given equation is -4 while the other is 1/4
we can tell if two lines are parallel when we get -1 when we multiply their slopes :)
\[(-4)\times\frac{ 1 }{ 4 } = -1\]

Answer 25

for the second one the answer is neither
