How do you graph and find the x-intercept and y-intercept for the linear equation x+3=0? Algebra Graphs of Linear Equations and Functions Horizontal and Vertical Line Graphs 1 Answer Shwetank Mauria Aug 6, 2018 No #y# intercept and #x#-intercept is #-3#. Explanation: A line such as #x+a=0# or #x=-a# is parallel to #y#-axis and hence no #y#-intercept, but #x# intercept is #-a#. Hence, here we do not have any #y# intercept and #x#-intercept is #-3#.
