Question

A line contains the points (0, -1) and (-1, 2). Another line graphed in the same coordinate plane contains the points (2,0) and (-2,3). Based on the slope of these lines, are they parallel, perpendicular or neither?

Answer 1

not sure but the slope is found by \[y _{2}-y _{1}\] over \[x _{2}-x _{1}\] If that's it then these lines are neither parallel nor perpendicular.
