Lowell's verbal representation of the equation y = x - 25 is "y is equal to x minus 25".
This verbal representation accurately describes the equation. In the equation, y is the dependent variable and x is the independent variable. The equation says that y is equal to x minus 25, which means that for every value of x, there is a corresponding value of y that is x minus 25.
So, Lowell has completed the task correctly.
