Answer:
y = 7x - 1
Explanation:
If a graph is shifted k units down, then the y-value (y-axis is the vertical axis) of the graph corresponding to a certain x-value reduces by k units.
Therefore, if the graph of the equation y = f(x) is shifted k units downward then the shifted graph will have the equation, y = f(x) - k.
In this case, the equation y = 7x + 5 is shifted by 6 units down, so the resulting equation will become
y = 7x + 5 - 6
⇒ y = 7x - 1 (Answer)
