anonymous · Answer

Every straight line can be represented by an equation: y = mx + b. The coordinates of every point on the line will solve the equation if you substitute them in the equation for x and y.

The slope m of this line - its steepness, or slant - can be calculated like this:
                                            m = change in y-value
                                                   change in x-value
