How do you find the slope of the line passing through the points A (3,9), B(1,5)? Algebra Graphs of Linear Equations and Functions Slope 1 Answer Leslie Apr 12, 2016 Slope = #2# Explanation: #A(3, 9) = (x_1, y_1)# #B(1, 5) = (x_2, y_2)# #Slope = (y_1 - y_2)/(x_1 - x_2)# #= (9 - 5)/(3 - 1)# #= 4/2 = 2# Answer link Related questions What is Slope?
