Parallel lines are lines that never intersect. Because of this, a pair of parallel lines have to have the same slope, but different intercepts (if they had the same intercepts, they would be identical lines). So, to find an equation of a line that is parallel to another, you have to make sure both equations have the same slope.

Apr 11, 2020 · Some parking lots have parallel spaces. These are usually marked clearly with white lines, so it can be easier to park in these than on the street. If you need to, drive around the block until you find a space with a large enough gap. You will need a space several feet longer than your car. Larger spaces are easier to park in.
• When the line is parallel to both HP and VP, there will be no traces on the said planes. Therefore the traces of lines are determined in the following positions of the lines. Lines perpendicular to one plane and parallel to the other. Lines inclined to one plane and parallel to the other. Lines inclined to both the planes.
Since motion and friction are parallel to the slope, it is most convenient to project all forces onto a coordinate system where one axis is parallel to the slope and the other is perpendicular (axes shown to left of skier).
The parallel sides are called the bases of the trapezoid and the other two sides are called the legs or the lateral sides (if they are not parallel; otherwise there are two pairs of bases). A scalene trapezoid is a trapezoid with no sides of equal measure, [3] in contrast to the special cases below.
