An identifiable path of a point moving in space.
A line is one-dimensional and can vary in direction, width and length. Lines often define the edge of a form. Lines can be horizontal, diagonal, vertical or curving and thick or thin. They can lead a viewer around a painting and communicate information through their characteristics whether they are actual or implied.
Actual lines are real such as painted lines on a road, tree branches, telephone poles or electric lines. The edges of objects are defined by contour lines, like the edge of a table, a boulder, the side of a building. Contour lines define the edges of the object and the negative space between them, such as the space fence posts.
Implied lines are lines that are interrupted and our mind fills in the space in between. Examples would be a row of windows on a building with wall space between, a row of separate plants in a garden, or fence posts lined up in a field. Our mind completes the line. Implied lines also can extend beyond the picture plane as with perspective lines.
