What is the slope of a line that passes through the point (−2, 3) and is parallel to a line that passes through (3, 7) and (−2, −8)?

Question

parthkohli · Answer

Determine the slope of (3,7) and (-2,-8).
A parallel line will have the same slope.

anonymous · Answer

How do I determine slope? What is the equation I would use?

parthkohli · Answer

$\Large \color{Black}{\Rightarrow {y_2 - y_1 \over x_2 - x_1} }$

binary3i · Answer

if two lines are parelel they have thew same slope.

anonymous · Answer

So the slope is three?

parthkohli · Answer

y2 is -8
y1 is 7.

x2 is -2
x1 is 3.

parthkohli · Answer

1/3 actually

parthkohli · Answer

So then the same slope would be the parallel line's slope.
So 1/3

anonymous · Answer

Ohh! I put y^1 - y^2 and x^1 - x^2 by mistake. And thank you so much, this is seriously a lifesaver right now !

binary3i · Answer

now 
y=mx+c
where you have m=3
y=3x+c
yous the point to get c
3=-2*3 +c
c=9
so the line is y=3x +9

Thanks!

parthkohli · Answer

Actually it's 3 oops

anonymous · Answer

Woah! I got it, okay, Messed up negative signs. It's 3!

parthkohli · Answer

I got confused. It's 3....GRR!
