It's straight E.

The best way is to solve this problem is to visualize it. We have the line k, which passes through the point (3, 2) and its parallel line m, which passes through the point (-3,2). If you draw one such pair and fix, then you can rotate them 360 degrees to get infinite number of line with negative as well positive slopes.

Answer: E.

For more on this issue please check Coordinate Geometry chapter of Math Book (link in my signature).

Hope it helps.

To find a slope we need at least 2 points on a line. Here only one point is given for each line.
