Answer 1

Neither parallel or perpendicular.

Explanation:

This is extremely simple. To determine if line E and line F are parallel or perpendicular, we need to compare their slopes.

The slope of line E is -67, and the slope of line F is 76.

Since the slopes are not equal and their product is not -1, line E and line F are neither parallel nor perpendicular.
