You can put this solution on YOUR website!

the equation of the line that contains
the point and P(4,-7), slope is undefined
In general, when the x-values or x-coordinates is the same for both points, the slope is undefined.The x-coordinate never changes no matter what the y-coordinate is! There is no run!
remember:
The slope of any vertical line is undefined.
The slope of any horizontal line is 0.
so, in your case line is vertical and equation is: x=a
if line passes the point and P(4,-7), equation will be x=4
