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?

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?

anonymous · Answer

Find Slope of both the equations and then compare:

If both are equal then the lines are parallel

And if product of both the slope is -1 then the lines must be perpendicular...

$$\large Slope = \frac{y_2 - y_1}{x_2 - x_1}$$
