The slope is mathematically 'undefined'. It is a line parallel to the y axis passing through x=-2x=2

Explanation:

By definition the slope (gradient) is ("change in y axis")/("change in x axis")change in y axischange in x axis

There is no change in the x axis. so we have ("change in y axis")/0change in y axis0 which is undefined
