How do you find the slope of #x + y = 7#? Algebra Graphs of Linear Equations and Functions Slope-Intercept Form 1 Answer SagarStudy Jan 20, 2016 #-1# Explanation: #x+y=7# #implies y=-x+7# #implies y=(-1)x+7# If #y=mx+c# is an equation then #slope=m and c=#y-intercept Here #y=(-1)x+7# #implies slope=-1# and y-intercept#=7# Hence slope of the line is #-1# Answer link Related questions What is Slope-Intercept Form?
