Answer:
The equation of the line is x=-6
Step-by-step explanation:
we know that
If the line has undefined slope, then we have a vertical line
A vertical line is parallel to the y-axis
The equation of a vertical line is equal to the x-coordinate of the point that passes through it
The line passes through (-6,-8)
so
The x-coordinate is -6
therefore
The equation of the line is x=-6
