What is the line equation of the line parallel to the y-axis and 3 units to the right of the y-axis?

A. X=-3

B. X=3

C. Y=-3

D. Y=3

B x = 3

the equation of a line parallel to the y - axis is x = c

where c is the value of the x-coordinate the line goes through

here the line is 3 units to the right of the y-axis, that is x = 3

thus equation is x = 3
