Question

Does anyone know how to graph y=x+1? I don't know how to do this because I am just learning this.

Answer 1

You may want to find some (x,y) pairs that fit in the equation

Answer 2

Find y when:
(a) x=-1
(b) x=0
(c) x=2

Answer 3

I have a question that tells me just to graph this and tell weather it is linear or non linear

Answer 4

I'm creating sub-questions to help you.

Answer 5

To judge whether it's linear, look at the degree.

Answer 6

There's no x^2 term or x^3 or any complicated stuff like that

Answer 7

There's just x and y, no other stuff

Answer 8

So it's linear

Answer 9

I am sorry I am not understanding what you are telling me.

Answer 10

Plug in any value for x.

let say x=0
y=x+1
y=0+1
y=1

So we know that when x=0, y=1. hence we have 1 coordinate that lies on the line, which is (0,1).

Let's do this again, .. choose a different number
lets say x=2
y=x+1
y=2+1
y=3

So we know that when x=2, y=3. hence we have another coordinate that lies on the line, which is (2,3).

graph 2 points, (0,1) and (2,3) and connect them with the line.

Answer 11

It'd be better to use three points because you don't know if it's linear. Then you might say if it's not linear you can't judge with three points, but well yeah.

Answer 12

@kc_kennylau she is just starting to graph those... she would get to that later.

Answer 13

okay...

Answer 14

I am confused sorry

Answer 15

Find y when:
(a) x=-1
(b) x=0
(c) x=2

Answer 16

Do you know how to name a point using x- and y-coordinates?

Answer 17

@fluteprincess352 look at what I wrote..

1) Do you see how I plugged 0 instead of x, and got the coordinate (0,1) ?

2) Do you see how I plugged 2 instead of x, and got the coordinate (2,3) ?

3) Do you know how to put a coordinate like (1,3) (3,4) and such.. on the graph ?

4) Do you see how I connected the 2 points with the line?

Answer 18

1. yes
2. yes
3. I think so
4. yes

Answer 19

Then why are you confused? :O

Answer 20

I don't know lol! I am terrible at math.

Answer 21

To verify number 3, can you graph (2, -2) and (-1,3) on the coordinate plane?

draw the 2 and say which one is which.
