Question

what would be two points on a graph for x7?

Answer 1

So if the graph is y = x^7, what would you go to get a y value?

Answer 2

I'm not sure that's how it is. Math is really confusing to me. All this has is that its undefined and its x=7. Doesn't undefined mean it has no y?

Answer 3

Ah, understood. Ill go step by step.

So if you want to find two points on a graph, you need X and Y coordinates.

Have you seen (x,y)? That would be a point on the graph.

But before I do this, did the problem say x=7 or x7 as in x to the power of 7? Like was the 7 a little number above the x?

Answer 4

it says x=7

Answer 5

Alright, so if y=7 is a HORIZONTAL line at the point y = 7, then x = 7 would be a VERTICAL line at the point x = 7.

Does that make sense so far?

Answer 6

kind of

Answer 7

So lets take a graph. Would you be able to find the X value of positive 7?

Answer 8

wouldn't it be (0,7)?

Answer 9

Almost

Remember the coordinate is (x,y)

Answer 10

oh, so (7,0)

Answer 11

Correct

Also known as x=7, see that?

Answer 12

Because the x in (x,y) is 7

Answer 13

I do. so how would I get a second point? Would it be (14,0) to be following the pattern?

Answer 14

If you want the second point to stay on the line x = 7, you can't change the x

For your example, (14,0), you changed the x. Now it reads that x = 14

The only thing you can change is the y

Answer 15

what would a second point be in that case?

Answer 16

You give me a guess. Remember those two things I said

You can't change the x
You can change the y

It's a line also, so lines never stop, which means you have an infinity amount of choices

Answer 17

so it would need to be up or down on 7x, right? it could be a positive or negative?

Answer 18

Right, the y value can be any number you wish

Answer 19

That makes sense. so for y=3, the y would stay the same but the x could be anything horizontal from that?

Answer 20

Correct!

So let's do y = 3

Since that means (x,y) is (x,3), the x can be any number, like literally

You can put (4,3) or (-3,3) or (6,000,000,000,000,000, 3), as long as the y value remains at 3

Answer 21

i get that part now. thank you! I have a huge project for my algebra class and my teacher isn't much help. would you be able to help me with graphing it as well?

Answer 22

Yeah, sure!

Answer 23

oh, crap, i have to go do something. do you have a kik account or anything?

Answer 24

I don't, but I'm on here, like alot. We could meet sometime later on here

Answer 25

I
should be back later today to finish, so that should work. Thanks a ton

Answer 26

Anytime! Bye

Answer 27

bye!
