What is the slope?

In the equation of a straight line (when the equation is written as "y = mx + b"), the slope is the number "m" that is multiplied on the x, and "b" is the y-intercept, where the line crosses the y-axis. This useful form of the line equation is sensibly named the "slope-intercept form". Graphing from this format can be quite straightforward, particularly if the values of "m" and "b" are relatively simple numbers (such as 2 or -4.5, rather than 17/19 or 1.67385). In this lesson, we are going to look at the "real world" ...
