Answer 1

@Vianne

Answer 2

I'm sorry. I'm not familiar with this. Haha xD

Answer 3

oh haha do you know anybody I can get help with maybe @Vianne

Answer 4

Set y to 0 for the x-intercept, and x to 0 for the y intercept.

Answer 5

Nope, sorry. :/

Answer 6

uhh I dont understand what you mean @a1234

Answer 7

x-3y=9
0 - 3y = 9
Can you do that for the y-intercept?

Answer 8

I know but the answer would be zero @a1234

Answer 9

How is that?

Answer 10

0-3*0=0 @a1234

Answer 11

You have to set x and y to 0 separately, not at the same time. Only one variable at a time.

Answer 12

Can you solve -3y = 9?

Answer 13

yeah

Answer 14

What is it?

Answer 15

3

Answer 16

x-3y=9
x/9 -y/3=1
then x intercept=3
and y intercept=-3
because x/a+y/b=1
x-intercept=a
y-intercept=b

Answer 17

-3, because it is negative.

Answer 18

-3 is the y-intercept.
Now can you do the x-intercept?

Answer 19

yes thank you @a1234

Answer 20

YW

Answer 21

sorry x-intercept is by mistake write 3.
