Identify the coefficient of
-24×7y

-24 × 7y
= - 168y
As coefficient is the numerical value so, the coefficient of -168y is -168

The coefficient is -27 and 7 I believe the variable(y) is called a parameter

When rates are expressed as a quantity of 1, such as 2 feet per second or 5 miles per hour, they are called unit rates. if you have a multiple-unit rate such as 120 students for every 3 buses, and want to find the single-unit rate, write a ratio equal to the multiple-unit rate with 1 as the second term.
