if there parallel its -3 but if there perpendicular the other lane must be positive:D

Two points don't have a slope. But the line between them does. The line between the points (-5, 3) and (3, 3) has a slope of zero.
-5/3 it is always the opposite reciprocal for a perpendicular slope
Slope of the given line is 3/7 So slope of perpendicular line is -7/3
Slope of given line = -3 Therefore, slope of perpendicular = 1/3
If they are parallel then the slope of the other line is also 7
