Coplanar Lines. Coplanar Lines are lines which lie on the same plane. Two parallel lines or two intersecting lines always lie in a plane. Thus, two line are coplanar, if and only if they are either parallel or intersecting. Lines in three dimensional space are coplanar, only if they are not skewed lines. Two lines which are neither parallel nor intersecting are called skewed lines.
That gives us the equations y = 0.5x + 7 and y = 0.5x â 1.5. Yes, the slope of both lines is 0.5, which means the lines really are parallel. They never intersect, so there is no point that lies on both lines, and no solution to the system. Micaela is trying to find the number of possible solutions for a system of two linear equations.
