Answer:
y = - 5
Step-by-step explanation:
y = 4 is a horizontal line parallel to the x- axis
A parallel line must therefore be a horizontal line with equation
y = c
where c is the value of the y- coordinates the line passes through.
The line passes through (1, - 5) with y- coordinate - 5, thus
y = - 5 ← equation of parallel line
