Answer:
x=3
Explanation:
x=5
D:[5]
R:(-∞,+∞)
since this equation represents a vertical line, slope of x is undefined, then, slope of line passing through 3,-10 is undefined too, since it is parallel
the equation of the second line is
y=undefined(3)
x=3
D:[3]
R:(-∞,+∞)
this is vertical line passing the x axis at 3
