Graph = with the -axis as the horizontal axis and the -axis as the vertical axis.The -intercept of () is indicated by the red dot at (=, =).. In analytic geometry, using the common convention that the horizontal axis represents a variable and the vertical axis represents a variable , a -intercept or vertical intercept is a point where the graph of a function or relation intersects the -axis of ...
The intercept theorem, also known as Thales's theorem, basic proportionality theorem or side splitter theorem, is an important theorem in elementary geometry about the ratios of various line segments that are created if two rays with a common starting point are intercepted by a pair of parallels.
In mathematics, a zero ... in this context is an -intercept. Solution of an equation . Every equation in the ... the first definition of an algebraic variety is ...
In mathematics, a linear equation is an equation that may be put in the form + … + + =, where , …, are the variables (or unknowns), and ,, …, are the coefficients, which are often real numbers. The coefficients may be considered as parameters of the equation and may be arbitrary expressions , provided they do not contain any of the variables.
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
Unlike the slope-intercept and intercept forms, this form can represent any line but also requires only two finite parameters, and p, to be specified. If p > 0 , then φ {\displaystyle \varphi } is uniquely defined modulo 2 π .
Although the definition here uses a parameterization of the curve, the notion of asymptote does not depend on the parameterization. In fact, if the equation of the line is a x + b y + c = 0 {\displaystyle ax+by+c=0} then the distance from the point A ( t ) = ( x ( t ), y ( t )) to the line is given by
Suppose that two lines have the equations y = ax + c and y = bx + d where a and b are the slopes (gradients) of the lines and where c and d are the y-intercepts of the lines. At the point where the two lines intersect (if they do), both y coordinates will be the same, hence the following equality: + = +.
