Question

X-2y=4

Answer 1

So, what do you need to do with that? That's not really a question on it's own....

Answer 2

What is the question?

Answer 3

Write y as function of x?

Answer 4

Oh do we need to graph this?

Answer 5

I have to find the x intercept and the y intercept

Answer 6

Yes

Answer 7

Ok for the x intercept:

Let y=o

Answer 8

x - 2(0) = ?
Whats the answer

Answer 9

2

Answer 10

Nope

Answer 11

Higher

Answer 12

It may be easier to write the function in standard form first. It will be easier to interpret.

Answer 13

0

Answer 14

Ok

Answer 15

y(x)=?x+?

Answer 16

x - 2(0) = 4
x - 0 =4
x = 4
So we have 4 as our x intercept

Answer 17

which is (4,0)

Answer 18

Do you get that?

Answer 19

So what would my y intercept

Answer 20

That is our next step. : Finding out the Y intercept

Answer 21

Ok so no questions on the x intercept.

Answer 22

To find out the Y intercept
We are going to let X=0

Answer 23

Ok

Answer 24

substituting that we get 0-2y=4

Answer 25

substituting that we get 0-2y=4
\[-2y/2 = 4/-2\]
and that gives us what?
