- mangadap.util.misc.line_coeff(p1, p2)[source]
Given two points on a line return the slope and intercept calculated as
\[\begin{split}m &= \frac{y_1 - y_2}{x_1 - x_2} \\ b &= y_2 - m\ x_2\end{split}\]- Parameters:
p1 (array-like) – A two-element \((x_1,y_1)\) array with one of the two points on the line.
p2 (array-like) – A two-element \((x_2,y_2)\) array with one of the two points on the line.
- Returns:
The slope (\(m\)) and intercept (\(b\)) of the line, respectively.
- Return type:
float
