Line g passes through points (5, 9) and (3, 2). line h passes through points (9, 10) and (2, 12). are line g and line h parallel or perpendicular?

For this case we find the slopes of each of the lines:

The g line passes through the following points:

So, the slope is:

Line h passes through the following points:

So, the slope is:

By definition, if two lines are parallel then their slopes are equal. If the lines are perpendicular then the product of their slopes is -1.

It is observed that lines g and h are not parallel. We verify if they are perpendicular:

Thus, the lines are perpendicular.

The lines are perpendicular.
