Answer:

Step-by-step explanation:
The points on the straight line are (P, 0) and (0, R).
The slope would be

And
, because the y-intercept is at (0, R).
So, the equation of this line would be

Where we multiply the equation by 

Therefore, the equation that represents this line is

<h2>
So, the right answer is B.</h2>
