Answer:
C
Step-by-step explanation:
Let x = price of one balcony seat and y = price of one orchestra seat
Price of orchestra seat = Price of balcony seat + 6
Or y = x + 6
Or 400y + 250x = 8250
Now that we have to two equations with two variables, we can use either substitution, elimination or graphing to find the prices of the seats.
I attached a picture of the graph. Remember since we set y as the price of the orchestra seat, the y coordinate in the point of intersection will be the price for one orchestra seat. This will be the same for the price of a balcony seat and the x coordinate.
Therefore, the price of one balcony seat is $9 and the price of one orchestra seat is $15.

Answer:
y = -4x + 9
O.R. y = 9- 4x
(both answers are equivalent, the same)
Step-by-step explanation:
1. finding gradient of perpendicular line to the equation given.
2. use the point provided in the wuestion and substitute it into the linear form of your slope-intercept form, which in my country is called the linear form, meaning straight line graph.
3. get answers by finding the y-intercept of the equation wanted.
note:
y = mx + c is how and what i use in my school as the linear form, altho every school is different and I understand that, so do check again with your teacher if it is how you do such type of questions.
