Answer:
y = 3 and x = 3
Explanation:
(11)
The equation of a horizontal line parallel to the x- axis is
y = c
where c is the value of the y- coordinates the line goes through
Here that is 3, thus
y = 3 ← equation of line
(12)
The equation of a vertical line parallel to the y- axis is
x = c
where c is the value of the x- coordinates the line passes through
Here that is 3, thus
x = 3 ← equation of line
