How do you graph #4x+y=-8# using intercepts? Algebra Graphs of Linear Equations and Functions Intercepts by Substitution 1 Answer Zain B. · Stefan V. May 14, 2017 #y#-intercept at #(0, -8)#. Explanation: #y = -4x -8# The #y#-intercept of a straight line #y=mx+c# is given by #c#. Here #c = -8#. so the graph intersects at #(0, -8)# with a gradient #m#, in this case #-4#. graph{y = -4x-8 [-10, 10, -5, 5]} Answer link Related questions What is the x and y Intercepts?
