line contains points (2, -2) and (-4, 1). Another line graphed in the same coordinate plane contains points (1, 2) and (-3, 4). Based on the slopes of these lines, are they parallel, perpendicular or neither?

Question

swissgirl · Answer

Ok so first we have to the slope of both lines

swissgirl · Answer

Do you remember the formula?

anonymous · Answer

y2-y1/x-x1

swissgirl · Answer

$ (2,-2)=(x_1,y_1)$
$(-4,1)=(x_2,y_2)$

anonymous · Answer

Parallel

swissgirl · Answer

$ \large {1-(-2) \over -4-(2)}=\frac{3}{6}=\frac{1}{2}$

swissgirl · Answer

ughhh its -1/2 i forgot the negative

anonymous · Answer

Parellel?

swissgirl · Answer

Try to find the slope of the second line
Use the same process

anonymous · Answer

I got parellel

swissgirl · Answer

Yes the lines are parallel since tehy both have the same slope but like i am assuming you have to solve it not just say its parallel
