to find the x coordinate we let y=0 likewise, to find the y coordinate we let x=0
LynFran
  • LynFran
so, y=-2(0)-3 and 0=-2x-3..just solve to get the respective coordinates
LynFran
  • LynFran
y=-3 -2x-3=0, -2x=-3 x=-3/-2 x=3/2

understand?

Sorry i went to the bathroom ^ ^;
LynFran
  • LynFran
ok...
LynFran
  • LynFran
so what are the x intercept as in (x,y)... and the y intercept as in (x,y) coordinates
anonymous
  • anonymous
1,2,3 for x and y is 5, 7, 9?
LynFran
  • LynFran
no...please read my 3rd comment
anonymous
  • anonymous
Alright.
LynFran
  • LynFran
ok lets go over x.. intercept
anonymous
  • anonymous
y = -2, 0, 3 x 0 = - 2x -3.
LynFran
  • LynFran
when we want to find the x intercept of a function we let y=0 ie (x,0) im change the function and replacing it with y=5x-5 ok as and example so, 0=5x-5..we replace y and put 0 we now solve for x 5x-5=0 5x-5+5=+5 5x=5 we then divide both sides of the equation by 5 to solve for x 5x/5=5/5 x=1..

  • anonymous
Alright thanks. Do i need to make a graph?
LynFran
  • LynFran
not always only if the question ask you to...so our x intercept for the given example would be (1,0)
anonymous
  • anonymous
Alright. Thanks a lot you'r a self savor :)
LynFran
  • LynFran
do u understand the y intecept part...if not i will go it over ok
anonymous
  • anonymous
It intercepts at 0 right?
LynFran
  • LynFran
we let the x intercept =0 ie (0,y) and we solve for y...what would be the y intercept for the given example i just give?
LynFran
  • LynFran
this one y=5x-5
anonymous
  • anonymous
x is equal to 0?
LynFran
  • LynFran
yes we let x=o and solve for y y=5(0)-5
anonymous
  • anonymous
Wouldn't that be 0 too?
LynFran
  • LynFran
no
LynFran
  • LynFran
y=5*0-5 y=0-5 y=-5
anonymous
  • anonymous
Okay. Think i got it now 5*0 = 0 and 0 subtracted by -5 is just negative 5.
anonymous
  • anonymous
-5*
LynFran
  • LynFran
yes now put it in coordinate form..(x,y) we get..
anonymous
  • anonymous
x= 0 and y= -5
LynFran
  • LynFran
very good (0,-5)
anonymous
  • anonymous
Thanks. I suck at math. XD
LynFran
  • LynFran
no problem but remember that was the intercepts for the example i give not for the problem you give ok
anonymous
  • anonymous
Yeah totally understand. That's why i try in solve them before i post them unless i really have no clue where to start.
LynFran
  • LynFran
ok just to note also in the case of sketching a graph..the x intercept is where the line/curve cuts the x axis on the graph...and the y intercept is where the line/curve cuts the y axis on the graph.

  • anonymous
Alright kool.
