Question

write an equation of the line containing the given point and parallel to the given line express answer in y=mx+b (7,8) ;x+7y=4
y=

Answer 1

Parallel means same Slope.

Answer 2

so what is the answer

Answer 3

now find b

8 = 7 (-1/7) + b

8 = -1 + b

b = 9

Answer 4

b=9 right

Answer 5

therefore:

y = mx + b

y = -1/7 x + 9

Answer 6

this is the ans.

Answer 7

what about this one it is what is the function f(x)=2-there is two lines and an x in the middle like this /x/

Answer 8

this is known as MOD.

in this, any value -ve or +ve... Always remains +ve.

Answer 9

| x |

Answer 10

so it remains the same and how did u type that ?

Answer 11

No, it always remains +ve.

Answer 12

o ok so what would it be and how do i work this problem out

Answer 13

to type that, there is a Pipe like thing above ENTER on your keyboard.

Answer 14

it is with the key of Back Slash.

Answer 15

o ok

Answer 16

a guy drew a Graph there, he was correct about it.

Answer 17

so how do we do this problem ?

Answer 18

well, ok look.

Answer 19

it is as simple as straight line graph.
like the line will cut the y-axis @ 2.
and its slope is -1.

but as the line is going to touch x = 0, it will reflect back.

Answer 20

if u didnt undersand that, then i will use another way.

Answer 21

ya use anothr way please

Answer 22

so in this case it will be (2,-1) right

Answer 28

a can we go back on that website and can u show me how to graph -1,-3 that goes with the equation y=-3-3x

Answer 29

OK!

Answer 30

Do u hav any more???

Answer 31

if not, thn i shall be leaving.
