Examples of line in the following topics:

  • Qualities of Line

    • Quality of line refers to the character that is embedded in the way a line presents itself.
    • Hard-edged, jagged lines present a staccato visual movement, while sinuous, flowing lines create a more comfortable feeling.
    • Horizontal, diagonal, and vertical lines describe a line's orientation.
    • Contour lines define the outer edges of an object.
    • Hatch lines are defined as parallel lines which are repeated short intervals generally in one direction.
  • Lines of Cleavage and Surgery

    • Cleavage lines are topological lines drawn on a map of the human body and correspond to the orientation of collagen fibers in the dermis.
    • Langer's lines, sometimes called cleavage lines, are topological lines drawn on a map of the human body .
    • Kraissl's lines differ from Langer's lines in that while Langer's lines were defined in cadavers, Kraissl's lines have been defined in living individuals.
    • The lines described by Kraissl differ in some ways from Langer's lines, particularly on the face.
    • Tension lines of the human skin.
  • Line

  • The Distance Between Two Lines

  • The Existence of Inverse Functions and the Horizontal Line Test

    • Recognize whether a function has an inverse by using the horizontal line test
  • Equations of Lines and Planes

    • A line is a vector which connects two points on a plane and the direction and magnitude of a line determine the plane on which it lies.
    • A line is described by a point on the line and its angle of inclination, or slope.
    • Every line lies in a plane which is determined by both the direction and slope of the line.
    • The components of equations of lines and planes are as follows:
    • Now, we can use all this information to form the equation of a line on plane $M$.
  • Line of Best Fit

    • The trend line (line of best fit) is a line that can be drawn on a scatter diagram representing a trend in the data.
    • The trend line, or line of best fit, is a line that can be drawn on a scatter diagram representing a trend in the data.
    • Trend lines typically are straight lines, although some variations use higher degree polynomials depending on the degree of curvature desired in the line.
    • The mathematical process which determines the unique line of best fit is based on what is called the method of least squares - which explains why this line is sometimes called the least squares line.
    • having the same number of data points on each side of the line - i.e., the line is in the median position;
  • Parallel and Perpendicular Lines

    • Two lines in a plane that do not intersect or touch at a point are called parallel lines.
    • This means that if the slope of one line is $m$m, then the slope of its perpendicular line is $\frac{-1}{m}$.
    • The value of the slope will be equal to the current line, since the new line is PARALLEL to it.  
    • The line $f(x)=3x-2$ in Red is Perpendicular to line $g(x)=\frac{-1}{3}x+1$ in Blue.  
    • Write equations for lines that are parallel and lines that are perpendicular
  • Contour Line

    • A contour line presents as a clean, connected line with no shading and emphasizes the open 'shell' of the visual subject.
    • Depending on how they are used, lines help to determine the motion, direction, and energy of a work of art.
    • The contour line is the simplest of the varieties of line.
    • A plain contour line presents as a clean, connected line with no shading and emphasizes an open 'shell' of the visual subject.
    • While contour lines create a path around the edge of a shape, cross contour lines follow paths across a shape to delineate differences in surface features.
  • Varieties of Line

    • There are six important varieties of line: actual, implied, straight, expressive, contour, and hatch lines.
    • The quality of a line refers to the character presented by a line in order to animate a surface to varying degrees.
    • 'Actual lines' are lines that are physically present, existing as solid connections between one or more points.
    • 'Hatch lines' are a series of short lines repeated in intervals typically in a single direction and are used to add shading and texture to surfaces.
    • Identify the basic varieties of line which are used in works of art.
