Vedclass · Answer

(C) The equation $x=a$ represents a vertical line parallel to the $y$-axis,passing through the point $(a, 0)$ on the $x$-axis.The equation $y=b$ represents a horizontal line parallel to the $x$-axis,passing through the point $(0, b)$ on the $y$-axis.When these two lines are plotted on the same Cartesian plane,the vertical line $x=a$ and the horizontal line $y=b$ intersect at exactly one point.The $x$-coordinate of the intersection point is $a$ and the $y$-coordinate is $b$.Therefore,the lines intersect at the point $(a, b)$.

The pair of equations $x=a$ and $y=b$ graphically represents lines which are
