Answer:
y = - 9
Step-by-step explanation:
y = - 2 is a horizontal line parallel to the x- axis.
A parallel line must also be horizontal with equation
y = c
where c is the value of the y- coordinates the line passes through.
The line passes through (7, - 9) with y- coordinate - 9, thus
y = - 9 ← equation of parallel line
