How do you find the x and y intercepts of x=1? Algebra Graphs of Linear Equations and Functions Intercepts by Substitution 1 Answer smendyka May 9, 2017 x=1 by definition is a vertical line where for every value of y, x will equal 1. So, for y=0, x=1 and the x-intercept is" 1 or (1,0) Because x is always equal to 1 it will never equal 0 therefore there is no y intercept.
