someone please help!

lgbasallote · Answer

point slope form is $$\huge y- y_1 = m(x-x_1)$$
where:
m = slope
x1 = x coordinate of the given point
y1 = y coordinate of the given point

does that help?

anonymous · Answer

not really so much..im kind of confused :(

lgbasallote · Answer

okay...what's your slope?

anonymous · Answer

-3 ?

lgbasallote · Answer

yes.

what is the x-coordinate of your point?

anonymous · Answer

umm...right there is where i get confused. :(

anonymous · Answer

is the x-cordinate (-1,6) ?

lgbasallote · Answer

|dw:1346381935950:dw|
does that help?

anonymous · Answer

ooooooooo ok i got it :D then what do we do?

lgbasallote · Answer

now you have

m = -3
x1 = -1
y1 = 6

agree?

anonymous · Answer

yes :D

anonymous · Answer

so its B?

lgbasallote · Answer

yes it's B. sorry for late reply

anonymous · Answer

its ok ":D and thank you sooo much!!
