Answer: Y = x + 7
Step-by-step explanation: We can translate the parent graph y = x, up or down by adding or subtracting a constant from the parent term x.
Since we want to write the equation of the line which represents a translation of y = x 7 units up, we need to add 7 to x.
So the equation y = x + 7 represents a translation of y = x 7 units up.
