Parallel lines have the same slope. So if you know the slope of a line in question, or you can calculate it, then you know the slope of any line parallel to that line.
It has the same slope as the line in the question. If a line has equation y = mx + c, its slope is m. If the line in question is y = 5x + 3, the slope of a parallel line is 5; If the line in question is y + 5x = 3 → y = -5x + 3 (subtract 5x from both sides), the slope of a parallel line is -5.
None of the ones in the question have any slope.

The slope of a curved line at a point is the slope of the tangent to the curve at that point. If you know the equation of the curve and the curve is well behaved, you can find the derivative of the equation of the curve. The value of the derivative, at the point in question, is the slope of the curved line at that point.
A line with slope of zero is horizontal. A line with no slope is vertical because slope is undefined on a vertical line.
Slope of a line = m slope of perpendicular line = -1/m
