Example 1 Find the slope of the lines: Passing through the points (3, –2) and (–1, 4) We know that slope between two points (x1, y1) & (x2, y2) is m = (𝑦_2 βˆ’ 𝑦_1)/(π‘₯_2 βˆ’ π‘₯_1 ) Here x1 = 3, y1 = βˆ’2, & x2 = βˆ’1, y2 = 4 Putting values Slope = (4 βˆ’ (βˆ’2))/(βˆ’1 βˆ’ 3) = (4 + 2)/( βˆ’4) = 6/( βˆ’4) = ( βˆ’πŸ‘)/𝟐
