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?

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

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

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
