Since this graph is a vertical line, there is no slope or y intercept. The slope in this case is undefined since the rise is any number (lets say 2) over a run of 0. So we get:
2%2F0 which is not possible to calculate. So the slope is undefined.
Since this graph is parallel to the y-axis, it will never intersect with the y-axis. This means the y-intercept doesn't exist in this equation
