14: to determine whether or not the slopes are perpendicular to one another is the negative reciprocal. In other words, if the first slope is <u>m</u>, the perpendicular slope is <u>-1/m</u>
to determine whether or not the slopes are parallel, the slopes are the same. In other words, if the first slope is <u>m, </u>then the parallel slope is <u>m</u>
<u />
So in other words: 1. perpendicular 2. neither 3. perpendicular 4. parallel
