So far we have seen that a straight line can be described as a line with a constant gradient and we know how to find the gradient of any particular line from a graph of the line. In this section we shall look more closely at the co-ordinates of points on a straight line to see ...
Often we just want an idea of what the line will look like so that we can sketch it instead of plotting lots of pairs, and so we consider the general equation of a straight line. The General Equation: The general equation of a straight line is: = + . We can tell 2 things about ...
2.2 The straight line: y = mx + c y = mx + c is called a linear function because its graph is a straight line. Notice that there are only two terms in the function; the x term, mx, where m is called the coefficient of x and c which is the constant term. m and c have spec...
The equation of a straight line is usually written this way: (or y = mx + c in the UK see below) y = how far up x = how far along b = value of y when x=0
The graph of an equation, in other words, is the graph of its solutions. It is the picture of those values of (x, y) that make the equation -- that statement -- true.Every first degree equation -- where 1 is the highest exponent -- has as its graph a straight line. (We prove...
The graph of an equation of the first degree. The slope-intercept form of the equation of a straight line.
The general equation of a straight line is y = mx + c, where m is the slope of the line and c is the y-intercept. There are different forms such as point-slope form, slope-intercept form, general form, standard form, etc.

The equation of a straight line is, y=mx+n. In the equation, m is the slope of the line. There are two critical cases: ∙m=0 when the line is parallel to the x-axis. ∙m→∞ when the line is parallel to the y-axis. Then, an equation of the form y=n, corresponds to ...
Equation of a Straight Line Two Point Form Slope Intercept Form of a Line Examples on y = mx + c Example 1: Find the equation of a line in the form y = mx + c, having a slope of 3 units and an intercept of -5 units. Solution: Given the slope of the line, m = 3, and th...
