The slope of the red line would be 5 as well as long as the lines are parallel. If it were perpendicular, or made an x, then the slope would be (1/5)<span />
If the lines described are parallel, this means that they will have the same slope. If the green line has a slope of 5, then the red one will also have a slope of 5. Parallel lines are those that do not meet. These lines do not touch or intersect at any point. Moreover, these lines are always the same distance apart (<em>equidistant</em>).
