Slope and the equation of a line
What slope measures, how to find it from two points, and how to write a line as y = mx + b.
The slope (or gradient) of a line measures how steep it is: how much changes for each step of 1 in . Lines rising to the right have positive slope; falling lines have negative slope.
Every non-vertical line can be written as , where is the slope and is the y-intercept (where the line crosses the y-axis).
