How do you find a slope of (-3,4) and (-5,-5)? Algebra Graphs of Linear Equations and Functions Slope 1 Answer E P. Apr 6, 2018 #m=(y_2-y_1)/(x_2-x_1)# Explanation: The formula for a gradient/slope #(m)# is: #m=(y_2-y_1)/(x_2-x_1)# #m=((-5)-(4))/((-5)-(-3))# #m=((-9)/-2)# #m=((9)/-2) = 4.5# Answer link Related questions What is Slope?
