Given the table for x, tickets sold and y, money earned:
x - # of tickets sold 4 9 8 5 7
y - $ earned 48 108 96 60 84
Every ticket sold is
12
dollars earned. This is called a
y-intercept
The relationship is
Linear and proportional
because there is a constant
rate of change
and 0 tickets sold means $0 earned.
is theis right?

Yes, that is correct. The relationship between the number of tickets sold and the money earned is linear and proportional because there is a constant rate of change ($12 for each ticket sold) and 0 tickets sold corresponds to $0 earned. This is also represented by the y-intercept in the table of values.
