Question

Given the coordinates of two points on a line, how is the slope of the line determined?

Accepted Answer

Determine the slope of a line by solving for the change in *y* over the change in *x*, or:   

$$slope = \frac{y_2 – y_1}{x_2 – x_1}$$

where $$(x_1, y_1), (x_2,y_2)$$ are points on the line.
