#### Explanation:

The slope of a line can be found by using the formula:

Where

The slope of the line passing through

The slope of the line passing through

Given a line with slope

The line perpendicular to the first line therefore would have a slope:

This is not the slope of the second line therefore these two lines are not perpendicular.

Using slope

#### Explanation:

Slope

And for 2 lines to be perpendicular the product of their slopes must be = -1

Therefore on finding the slopes we get

But

Hence they are not perpendicular
