Question

What are the intercepts of the line X-3y=9




A X-intercept:-3; Y-intercept:-9
B X-intercept:3; Y-intercept:9
C X-intercept:-9; Y-intercept:-3
D X-intercept:9; Y-intercept:-3

Answer 1

just plug 0 in for x then solve to get y intercept and plug in 0 for y to get x intercept

Answer 2

x - 3y = 9
(0) - 3y = 9 solve for y u get y-intercept

Answer 3

yes u are correct

Answer 4

what do i do next

Answer 5

no i thought u meant it's the answer 9 and -3........ solveing for y u should have
y = 9/-3

Answer 6

thats -3

Answer 7

yes

Answer 8

yup because ur saying y = -3 when x = 0 that is where the graph will cross the y-axis (0,-3)

Answer 9

u want to find where the graph crosses the x axis by setting y = 0 and solve for x

Answer 10

x - 3y = 9
x -3(0) = 9 solve for x

Answer 11

your welcome i hope ur able to understand it better

Answer 12

well what answer did u get for x?

Answer 13

-3(0) = 0 so x = 9

Answer 14

oh so is D

Answer 15

yes good job

Answer 16

thank u so much

Answer 17

it might help if u do this problem again later or tomorrow .... practicing will help just a suggestion. yeah your right i'm am pursuing to become a math teacher.

Answer 18

your welcome glad i could help

Answer 19

ty very much

Answer 20

i'll try to help, i don't know everything lol

Answer 21

do i just plug in the numbers and see what works

Answer 22

think y intercept solve for y when x = 0......... yes.....think x intercept and solve for x when y = 0.

Answer 23

ok thanks

Answer 24

you could do it and plug those numbers from the multiple choice but u'd have to do them separate and if they = each other then that would be one of the intercepts then do the other.......u could think of it x= 0 then y intercept could be plugged into the equation...either way u should get same answer. there are usually a lot of ways to solve problems.

Answer 25

whatever way u feel comfortable with you should use. doesn't hurt to know more than one way though

Answer 26

ya

Answer 27

bye

Answer 28

u get the answer?

Answer 29

u understand how to set it up ? y intercept is when x = 0 cuz the coordinate will be (0,y) on they axis.... same for x just reverse

Answer 30

so answer would be (3,0) and (0,-2)......... the set up u could say
6x -9y =18 for y intercept use x = 0 and 6x-9y =18 for x intercept use y = 0
6(0) - 9y =18 6x-9(0)=18

Answer 31

the other way to plug in numbers would be
6(-3) -9(2) = 18 set both to 2 equations like 6(-3) = 18 and -9(2) = 18 u find out neither equal 18 so u'd try next answer. this strategy might take longer though

Answer 32

glad u got it

Answer 33

nice keep up the good work. education is such a vital asset so keep striving. your welcome

Answer 34

cool yw take care

Answer 35

ur asking me y i helped u?
