Question

graph the equation by plotting three points
x -4y=-18

Answer 1

From this equation you can find infinite number of points. Do so find plugging in 0,1,-1 for x and looking for y

Answer 2

i dont get this?

Answer 3

x - 4y=18

Answer 4

its supposed to be x - 4y=-18

Answer 5

y intercept...y=18/4
x intercept...x=18
its a straight line with a gradient of 1/4 so its an increasing straight line

Answer 6

what?....... y =18,4

Answer 7

its supposed to be 3 points

Answer 8

the only thing you can get from the graph is gradient and intercepts

Answer 9

oh okhay i dont know what gradients mean

Answer 10

to get 3 points do as follws:

first put x=2 and u get
2 -4y = -18
-4y = -18 -2
y = -20/-4
y = 5
so first point is (x,y) = (2,5)

Answer 11

Slope

Answer 12

first put x= -2 and u get
-2 -4y = -18
-4y = -18 +2
y = -16/-4
y = 4
so second point is (x,y) = (-2,4)

Answer 13

okhay what are the next 2 points?

Answer 14

lol, girlie, you dont know what a gradient is?, OMG, thats suprising

Answer 15

wow it surprised me too.

Answer 16

finallyput x= -6 and u get
-6 -4y = -18
-4y = -18 + 6
y = -12/-4
y = 3
so third point is (x,y) = (-6,3)


Now plot these three points and join them with a line to get the required graph of the equation

Answer 17

Gradient is called Slope is U.S

Answer 18

@minah

got it??????

Answer 19

ummm im from america ...... yes harkirat i got it you deserve a medal thanks sweetie

Answer 20

whenever they ask you to plot by taking three points follows this procedure...

Answer 21

@HARKIRAT okhay but i really suck at it =)

Answer 22

O SORRY GIRL YOU NEED MORE PRACTICE BECAUSE IM ALSO FROM THE USA.

Answer 23

YEA YOU ARE SORRY , BUT UMM JUST BECAUSE I DONT KNOW WHAT THAT MEANS DON'T MEAN NOTHING OKHAY? EINSTEIN

Answer 24

ok, stop with all caps

Answer 25

ok goodluck in your math practice
pray be4 you study, trust me, it works,God bless!!!

Answer 26

thanks guys/girls for the help =) everyone!!

Answer 27

@einstien ----
All fingers are not alike and no two minds are alike.
Can u sing like MJ or dance as good as MJ

Answer 29

Do I get a medal for this too !!! :D:D:D

Answer 30

yeahhh i already gave you one i dont know how to give you another ... but you could help me more when i ask for questions for more medals

Answer 31

just joking.........

if i am online i will definitely help.....

Answer 32

you know great mathematicians and scientists like me dont care about the grammar but care about the figures instead, sorry.

Answer 33

ok i wil give every one a medal

Answer 34

I think u hv a long way before u can b called "great mathematician and scientist". win a Nobel Prize for something that u hv done and i will bow before u !! Being able to do successfully something that others have developed is no genius !!!

Answer 35

my friend i hate essays go and write a novel for my granny to read

Answer 36

Oh so others have to take of your granny's needs !! don't u care for her??
