The -intercept of () is indicated by the red dot at (=, =). In analytic geometry , using the common convention that the horizontal axis represents a variable x {\displaystyle x} and the vertical axis represents a variable y {\displaystyle y} , a y {\displaystyle y} -intercept or vertical intercept is a point where the graph of a function or ...
A non-vertical line can be defined by its slope m, and its y-intercept y 0 (the y coordinate of its intersection with the y-axis). In this case, its linear equation can be written = +. If, moreover, the line is not horizontal, it can be defined by its slope and its x-intercept x 0. In this case, its equation can be written
The y-intercept point (,) = (,) corresponds to buying only 4 kg of sausage; while the x-intercept point (,) = (,) corresponds to buying only 2 kg of salami. Note that the graph includes points with negative values of x or y , which have no meaning in terms of the original variables (unless we imagine selling meat to the butcher).
Intercept may refer to: X-intercept, the point where a line crosses the x-axis; Y-intercept, the point where a line crosses the y-axis; Interception, a play in various forms of football; The Mona Intercept, a 1980 thriller novel by Donald Hamilton; Operation Intercept, an anti-drug measure announced by President Nixon
This following list features abbreviated names of mathematical functions, function-like operators and other mathematical terminology. This list is limited to abbreviations of two or more letters (excluding number sets). The capitalization of some of these abbreviations is not standardized – different authors might use different capitalizations.
Conversely, any line through (x, y) satisfies the original equation, so al + bm + c = 0 is the equation of set of lines through (x, y). For a given point (x, y), the equation of the set of lines though it is lx + my + 1 = 0, so this may be defined as the tangential equation of the point. Similarly, for a point (x, y, z) given in homogeneous ...
The ray can be formed by any wave: optical, acoustic, microwave, X-ray, etc. angle of reflection The change in direction of a wavefront at an interface between two different media so that the wavefront returns into the medium from which it originated. Common examples include the reflection of light, sound, and water waves.
An arrow with an opposite direction compared to another arrow. The arrow (y, x) is the inverted arrow of the arrow (x, y). isolated An isolated vertex of a graph is a vertex whose degree is zero, that is, a vertex with no incident edges. [2] isomorphic Two graphs are isomorphic if there is an isomorphism between them; see isomorphism. isomorphism
