What are the intercepts for #x=4#? Algebra Graphs of Linear Equations and Functions Intercepts by Substitution 1 Answer Alan P. Sep 29, 2015 x-intercept: #4# There is no y-intercept. Explanation: #x=4# is a vertical line running parallel to and not crossing the Y-axis; therefore there is no y-intercept. #x=4# for all values of #x# and specifically at the point where the line crosses the X-axis Answer link Related questions What is the x and y Intercepts?
