Answer:
y = 12
Explanation:
y = 8 is the equation of a horizontal line, parallel to the x- axis.
Thus a parallel line will also be horizontal.
The equation of a horizontal line is
y = c
where c is the y- coordinates of the points it passes through.
The line passes through (- 6, 12) with y- coordinate of 12, thus
y = 12 ← equation of parallel line
