We are to find the equation of a line whose slope is undefined
Having x-intercept = 10
Since the slope of the line is undefined, then the line is a vertical line
Hence,
The equation will be in the form
[tex]x=a[/tex]
Where a is the x value
Therefore,
The equation of a line whose slope is undefined and whose x-intercept = 10 is
[tex]x=10[/tex]
