For the first equation, use the point slope formula and plug in the given data

  • anonymous
y+4=(-1/3)(x-6) ----->Now rearrange this if it is required. You can leave it like this since it is correct.

And for the second part, find the slope between the two points: (-6,1) and (-4,2).. And use one of the points to form the equation.

it has 2 b completely simplified and 4 the first 1 got y=-1/3x-6
anonymous
  • anonymous
huh?
anonymous
  • anonymous
It would have helped if you would spell out the words. And no, it is not y=-1/3x-6. Instead it is y=-1/3x-2
anonymous
  • anonymous
oh ok I see what I did wrong and sry im trying 2 type with 1 hand and it takes longer so im using short cuts
anonymous
  • anonymous
For the second part, can you find the slope between the two points?
anonymous
  • anonymous
The slope would be 1/2. Now pick either point and write the equation.
anonymous
  • anonymous
y-2=1/2(x+4)----> Now rearrange this and get y=1/2x+4
anonymous

Hope this helped.

ok thanks :) do you understand this problem : Write the equation of the line with an undefined slope, passing through the point (2, 5).
anonymous
  • anonymous
I don't understand how u can write an undefined slope
anonymous
  • anonymous
undefined slope means the line is vertical. Therefore, the equation for the line would be y=2
anonymous
  • anonymous
wait, x=2.
anonymous
  • anonymous
so you don't do anything with the 5?
anonymous
  • anonymous
y=2 would be horizontal, so it would be x=2
anonymous
  • anonymous
5 is a point above the 2. Only the first variable matters, which is 2.

oh ok :) thank u sooo much
