\[x+2y=0\]

solve it for what? do you want x-intercepts, y-intercepts. finding these will be useful in graphing.
anonymous
  • anonymous
Ok I need to find M and B if that makes sense. So yeah x and y intercepts.
myininaya
  • myininaya
you need to write in slope intercept form: y=mx+b solve the equation above for y by subtracting x first let me know what you have after you do this
anonymous
  • anonymous
0+2y=-1?
myininaya
  • myininaya
what happen to the x?
myininaya
  • myininaya
2y=-x
anonymous
  • anonymous
and thats it?
myininaya
  • myininaya
no its not in this form y=mx+b yet what do we need to do next
anonymous
  • anonymous
Divide by two?
myininaya
  • myininaya
right so we have y=-x/2 so what is m=? and what is b=?
anonymous
  • anonymous
m=1\1 b=0
anonymous
  • anonymous
Is that right?
myininaya
  • myininaya
m=-1/2 and b=0
anonymous
  • anonymous
ok. How would you do y=-4
myininaya
  • myininaya
y=-4 is a horizontal line going through -4 on the y axis
anonymous
  • anonymous
Ok so let me give you a problem. Me work it out and will you tell me if its right?
anonymous
  • anonymous
My next problem is: 2x+3y+6
anonymous
  • anonymous
y=2\3=2 m=2\3 b= 2
myininaya
  • myininaya
what did you write for the y=mx+b form
anonymous
  • anonymous
y=2\3x=2
myininaya
  • myininaya
2x+3y=6 -2x -2x 3y=-2x+6 _ _ _ 3 3 3 y=-2x/3+2 so the slope is m=-2/3 the y intercept is b=2

One more equation I just dont get.
anonymous

x-2y=-4
