The answer to your question is:
Step-by-step explanation:
If the line is rotated, we get the perpendicular of the initial line.
See the attachment, the blue line is the original and the red one is the new line.
Process
new slope = 2/5
Point ( 0, 4)
(y - y1) = m (x - x1)
( y - 4) = 2/5 (x - 0)
y - 4 = 2/5 x
y = 2/5 x + 4 New line
