Linear equations are represented by straight line.
The required graph is graph (a).
The given parameters are:
Let x represents the number of weeks, and y represents the number of words in week x.
So, we have:
Substitute 15 for Rate
The above equation means that:
The graph that represents the above ordered pair is graph (a).

Answer:
15 early tickets were sold and 5 regular tickets were sold.
Step-by-step explanation:
Let x be the number of early bird tickets sold and y be the number of regular tickets sold.
Total number of tickets sold = 20
Thus, we can write the equation,
Cost of early bird ticket = $10
Cost of regular tickets = $15
Total cost = $225
Thus, we can write the equation,
We solve the equation by elimination method by multiplying first equation by 10 and subtracting.
Thus, 15 early tickets were sold and 5 regular tickets were sold.
