Graphs are used to represent pictorially or clarify a relationship between two variables, say x and y, or t and function (t). If x and y are related by the linear equation y = mx + c, then the graphical relationship is a straight line as in Figure 1.1, where m is the slope, a constant value for a straight line and c is the value of y when x = 0. Figure 1.2 shows the relationship when m and c take negative values. Note that if c = 0, the line passes through the origin, 0, of the x–y axes. Examples of other linear relationships that can be represented in this way include the following (the bracketed symbols are the variables equivalent to x and y above): v = u + a t; (variables are t and v), where u is the starting velocity of an object that is subjected to acceleration a for time t, after which its velocity is v.
