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

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

i dont get this?

x - 4y=18

its supposed to be x - 4y=-18

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

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

its supposed to be 3 points

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

oh okhay i dont know what gradients mean

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)

Slope

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)

okhay what are the next 2 points?

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

wow it surprised me too.

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

Gradient is called Slope is U.S

@minah got it??????

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

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

@HARKIRAT okhay but i really suck at it =)

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

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

ok, stop with all caps

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

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

@einstien ---- All fingers are not alike and no two minds are alike. Can u sing like MJ or dance as good as MJ Can u play tennis like Roger or Nadal?? Each of us has our own pace of learning as long as we keep trying and improving, it is okay..... PS : You seem to have problems with spellings!!! Its Einstein and not eistein !!

wow nicely said...

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

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

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

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

ok i wil give every one a medal

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 !!!

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

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

omg GUYS please stop!!!!!!! your both smart people...... don't argue over dumb things =)

lol dude cumon. lets stop.

minah, he has chosen the names of great but very humble people but seems to be too full of himself. it is not good to look down upon others.....that's all

Ok Peace !!!

thanks help me again =)
