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.
