How do you determine the slope and y intercept when given a graph? Algebra Graphs of Linear Equations and Functions Slope-Intercept Form 1 Answer Wataru Oct 29, 2014 The #y#-intercept #b# can be found by reading the #y#-axis where the graph hits the y-axis, and the slope #m# can be found by finding any two distinct points #(x_1,y_1)# and #(x_2,y_2)# on the graph, and using the slope formula below. #m={y_2-y_1}/{x_2-x_1}#.
