what is the slope of a line that passes through the point (-1, 1) and is parallel to a line that passes through (4, 6) and (-1,-4)?

Question

anonymous · Answer

The slope of parallel lines is the same. 
So first find the equation of the line for (4,6) and (-1,-4)

(-10)/(-5)=2

So we plug in for the point (-1,1):
y-1=2(x+1)
=2x+3

so rise over run..wait is that the slope?

anonymous · Answer

Oh sorry, ya I didnt label my slope. 
slope is $$m=\frac{ y-y1 }{ x-x1 }$$

anonymous · Answer

So that was what I was doing with (-10)/(-5), plug in the points.

anonymous · Answer

right, so slope is -2/-1?

anonymous · Answer

ya so its 2 it doesnt matter what order you plug in the points

anonymous · Answer

Did it work?

anonymous · Answer

the slope is 2 or -2? I think it's working!

anonymous · Answer

The slope is 2 since (-2)/(-1) simplifies to just 2.
