Equations Of Lines Equations Of Lines A linear equation is an algebraic equation in which each term is either a constant or the product of a constant and a single variable. More than one variable could be occurred by the linear equations. There is a great regularity of linear equations in applied mathematics. The origin of the linear equation comes from the fact that the set of solutions of such an equation forms a straight line in the plane. A straight line on the coordinate plane could be described by the equation y = mx + c, This is also named as the general Equation of Lineor slope intercept form. Here ‘x’, ‘y’ are the co ordinates of any point on the lines ‘c’ is the y - intercept and m is the slope or gradient of the line that is, Know More About : Multiplying Square Roots Calculator

m = change in y / change in x. Sometimes the words “rise” and “run” are used. Rise refers the same meaning as y that’s how far up and run refers the same as ‘x’ that’s how far along mean the slope is m = rise / run, The slope of the line 'm' is steepness of the line and c is named as intercept means the line crosses the y– axis. Two others forms of the equation of a line are, Ax + Bx = C [This is sometimes called the standard form also], Where ‘A’ and ‘B’ are not equals to zero. All the three A, B and C are the co prime integers and the constant ‘A’ doesn’t have the negative value and if ‘A’ is zero then definitely B must be positive. The standard form could be convertible to the general form but it’s not always possible to convert in the other forms if ‘A’ and ‘B’ is zero. And x = a, A line parallel to the y – axis means equation of the vertical line through the point (a, b). Read More About : Multiplying Exponents Calculator

or y=b Is an equation of horizontal line through the point (a, b). If a particular point on a line and the slope of a line are known as equation for that line is written at the point (x1, y1) using point slope form, y – y1 = m (x - x1), This form of equation is also named as point slope form. The equation of two point form of the line is written as, y – y1 = y2 – y1 / x2 – x1 (x – x1), Where (x1, y1) and (x2, y2) are two points on the line with x2 is not equal to ‘x1’. This is the same as to the point slope form explained above where the slope is given as y2 – y1 / x2 – x1. Some properties of lines are, If two non vertical lines are parallel then the slope of those lines would be same. If two non vertical distinct lines have the same slope then those lines are parallel. If two non vertical lines are perpendicular then the product of the slopes of those lines is -1. If the product of the slopes of two lines is -1 then those lines would be perpendicular to each other.The equation of line is used for defining a particular line in a compact way and to locate the points on the line.
