The slope of a line is given by which of the following:

m = x1x2y1y2m\ =\ \frac{x_1-x_2}{y_1-y_2}

m = y1y2x1x2m\ =\ \frac{y_1-y_2}{x_1-x_2}

y = mx + by\ =\ mx\ +\ b

y y1= m(xx1)y\ -\ y_1=\ m\left(x-x_1\right)

The point-slope form of a line is given by

m = x1x2y1y2m\ =\ \frac{x_1-x_2}{y_1-y_2}

m = y1y2x1x2m\ =\ \frac{y_1-y_2}{x_1-x_2}

y = mx + by\ =\ mx\ +\ b

y y1= m(xx1)y\ -\ y_1=\ m\left(x-x_1\right)
