Answer:

C. Equation: x=4

D. Slope: undefined

Step-by-step explanation:

If a line is perpendicular to the x-axis, then it is a vertical line because the x-axis is horizontal.

The slope of a vertical line is undefined.

The equation of a vertical line through [tex](x_1,y_1)[/tex] is [tex]x=x_1[/tex]

Since the vertical line passes through (4,-2), its equation is

[tex]x=4[/tex]
