Question

anonymous · Answer

Alright first you must find the slope of the line using that last equation you used

saifoo.khan · Answer

slope!

yo yo yo

anonymous · Answer

m= (y1-y2) over (x1-x2) right?

saifoo.khan · Answer

right

anonymous · Answer

You should get 3 = m

anonymous · Answer

I did. I'm clueless as to what to do after.

anonymous · Answer

It says form the equation? I'm sorry, I missed tons of classes and am only cramming now.:)

anonymous · Answer

alright so there is another equation you need- Point slope form

which is

$$y-y _{1}=m(x-x _{1)}$$

anonymous · Answer

have you seen this equation?

anonymous · Answer

I have. Just substitution, right?

anonymous · Answer

yes, with either point. With the first, you should get

y-2=3(x-3)
y-2=3x-9
y=3x-7

anonymous · Answer

I did. Thank you so much for you help! Salamat! :)

*your

anonymous · Answer

with the second you'll get

y+4=3(x-1)
y+4=3x-3
y=3x-7 

*just showing either way

Thank you, thank you, thank you! :)
