 Find the slope from two points Determine the slope of a line from two points You can determine the slope of a line finding two points P(x 1,y1) and Q(x2,y2) on the line and using the following equation: $m=\frac{y_2-y_1}{x_2-x_1}$ Look at the picture and determine the slope: $m=\frac{1-2}{4-(-3)}=\frac{-1}{7}$
