x - y² - 3y → a
The y- term has a coefficient (number in front of the variable) of - 3
The x-term has a coefficient of 1 ( x represents 1x)
There is no constant term ( that is, no numeric value )
The y² term has a coefficient of - 1 but is not included in the description given.
The expression could therefore be x - y² - 3y
