Properties of linear equation

A quick introduction to linear equations, their characteristics, and some of the terminology used in understanding the parts of linear equations. The general.. Linear Equations: All lines, when graphed on the coordinate plane, have a constant rate of change, or slope, and can be represented by a linear equation An equation for a straight line is called a linear equation. The general representation of the straight-line equation is y=mx+b, where m is the slope of the line and b is the y-intercept. Linear equations are those equations that are of the first order. These equations are defined for lines in the coordinate system The same goes with the subtraction property of equality. i f a + b = c, t h e n a + b − b = c − b, o r a = c − b. As well as it goes for the multiplication property of equality. If you multiply each side of an equation with the same nonzero number you produce an equivalent equation. i f a b = c, a n d b ≠ 0, t h e n a b ⋅ b = c ⋅ b. A linear equation with one variable130, x, is an equation that can be written in the standard form ax + b = 0 where a and b are real numbers and a ≠ 0

A linear equation is an equation for a straight line. These are all linear equations: y = 2x + 1 : 5x = 6 + 3y : y/2 = 3 − x: Let us look more closely at one example: Example: y = 2x + 1 is a linear equation: The graph of y = 2x+1 is a straight line . When x increases, y increases twice as fast, so we need 2x Linear functions can be represented in words, function notation, tabular form and graphical form. The rate of change of a linear function is also known as the slope. An equation in slope-intercept form of a line includes the slope and the initial value of the function
