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?
