x = 2

Answer 3

can you show how you got that please

Answer 4

Parallel to y-axis means the line has to be a vertical line. Vertical lines have constant x value. All points on that line have the same x-coordinate and infinite number of y coordinates. Because the line passes through 2,-4, the line's equation has to be x=2.
