Consequently, the equation determining the remaining number of rooms Martin has to clean after hours can be represented as:

$y=-\frac{4}{7}x+b$

, in which $b$ indicates the overall number of rooms. Step-by-step explanation: It is given that Martin has 4 rooms left to clean and takes 7 hours for the task. The equation in standard form for the number of rooms remaining after x hours, y, is set up as follows: The remaining rooms $y$ , indicates the quantity after $x$ hours. The cleaning rate is established as follows: Considering Martin cleans 4 rooms in 7 hours, the rate at which he cleans is given by: Hence, the equation can be expressed as

$y=-\frac{4}{7}x+b$ (Answer)
