Answer:

d) intersecting, but not perpendicular lines

Step-by-step explanation:

Changing the sign of one of the variable terms causes the line to be reflected across one of the axes. The slope is the opposite of what it was. Since the original slope was not 1 or -1, the resulting line is not perpendicular to it. Lines with different slopes will be intersecting.

The two lines are intersecting, but not perpendicular.
