Question

I feel very dumb right now, I forgot how to graph a linear equation when it is only a problem that says this:

x-y=2

Answer 1

when x=0, y=?
when y=0, x =?

plot those 2 points and there is your line :)

Answer 2

substitute one value of x ...find y and plot it on graph ..like x=1,2,3...y=??? and plot it

Answer 3

So basically choose any number.

Answer 4

yes

Answer 5

but only for one variable...like either for x or for y

Answer 6

Alright. Then I solve for the other variable.

Answer 7

yes....like if you consider x=1 you'll get y= x-2= 1-2= -1

Answer 8

now you have one pair (1,-1) similarly find at least one more pair and plot it :)

Answer 9

I wish math was a lot more simple.

Answer 10

:) it is ...it's an art...like writing ...i guess art of writing is more complex than maths :)

Answer 11

I am better on writing than I am math.

Answer 12

do you write?

Answer 13

Yes, all the time. The teacher when I went to the class kept some of my work to show future students when she train.

Answer 14

wow!! :)

Answer 15

I wish my math was like that.

Answer 16

you'll have it...with small amount of practice....

Answer 17

I hope so, I have 28 questions to do all mixed up with various problems but has to do with Linear equations. Then I have a test to do, but I have to get it all done before midnight tonight.

Answer 18

shoot your questions

Answer 19

Alright, as for this one I might just do 0 for the x and solve for y. (If I remember the function to do it).

Answer 20

yes...put x=0 and find y

Answer 21

0-y=2 would be y=-2.

Answer 22

yes

Answer 23

(0,-2) then. Now I just have to graph the thing.

Answer 24

nope...consider another point let's say x=1 now find y

Answer 25

what you got?

Answer 26

y would be -1.

Answer 27

yes ...now you have (0,-2) and (1,-1) now plot it on graph and join these two points

Answer 28

Alright, got that one done.

Answer 29

done...?

Answer 30

That question lol.

Answer 31

so no more questions??? :)

Answer 32

Oh there is more lol, just the one i am working on I am trying to do myself. This one is 2x+3y=-6. It reminds me of the y=mx+b formula.

Answer 33

so what you have to do in this?

Answer 34

Graph it, but to do that I will have to find the x and y.

Answer 35

so do it again...consider x=0,1 and find y at these x
