Answer:
No, this rel. is not proportional because of the addition involved ("plus 1 lb for each guest").
A proportional rel. features mult. only.
Explanation:
et x represents the number of guest and y represents the number of pounds of chicken made,
Given,
The number of pounds of chicken for each guest = 1,
So, the number of pounds for x guests = x,
Also, the number of pounds already made =
Thus, the total pounds of chicken,
Since, a relation is called proportional if the variables are directly proportional,
That is, the line obtained by the relation passes through the origin,
Since, if x = 0, y = 0,
∴ Line does not pass through the origin.
