## Intercepts and slope of the line equation

Previously we have discussed about area of octagon calculator and In today’s session we are going to discuss about Intercepts and slope of the line equation, Equations are of various forms like linear equations. quadratic equations, logarithmic equations etc., and graphing of all types of these mathematical equations is also done. But while doing graphing or we can say to draw 2D pictorial representation two terms are essentially required which are co-ordinates of Cartesian axes and Intercepts. Let us discuss about Intercepts. Intercepts are the intersection points or the points at which the line of the equation crosses the graph. While graphing of any mathematical equation we need both X and Y intercepts. When we talk about X intercepts it means all the y axis points are zero and similarly in case of Y intercept all the x axis points are zero.

In general form we can represent X intercept as ( x, 0) and Y intercept as ( 0, y).

With this phenomenon we can find the endpoints of any line equation, like for finding y coordinates just put x = 0 in the algebraic equation and for finding x coordinates put y= 0 in equation because of intercepts theory.

Apart from intercepts, slope of the line is also required to graph the mathematical equation.

The general form of slope equation is as:

y = mx + c

Here m denotes the slope of the line which is also represented as:

m = dy/dx= tan (angle)

For finding slope of the line slope formula is used which is —> m = (y2 – y1) / (x2 – x1)

here (x1, y1) and ( x2, y2) are endpoints of the line, but using slope formula there is only one  condition that both x axis points cannot be same. x1 is not equal to x2.

To learn more concepts on intercepts and slope formula you can prefer online math tutoring website, TutorVista , which covers all the lessons of this topic and other math topics.
