Answer:
Given point is: (-3,9)
To find the equation of vertical and horizontal line passes through the point.
Vertical line:
A vertical line is parallel to the yaxis and we know that equation of y axis is x=0
The equation of the vertical line is x=k where k is any constant
Since the line passes through the point (-3,9), k is equal to the x-coordinate of the point.
k=-3
we get,
the equation of the vertical line is x=-3
Horizontal line:
A horizontal line is parallel to x axis and we know that equation of x axis is y=0
The equation of the horizontal line is y=h where h is any constant
Since the line passes through the point (-3,9), h is equal to the y-coordinate of the point.
h=9
we get,
the equation of the horizontal line is y=9
