Question

what type of lines do the pair of equation x=c and y=c represent graphically ?

Answer 1

The line x = c

This line is a vertical line passing through point (c, 0) on the graph

For example x = 3 is a vertical line drawn at the point (3, 0


The line y = c

This is a horizontal line passing through point (0, c)

For example y = 4 is a horizontal line drawn at point (0, 4)

Answer 2

mutually perpendicular
