Answer:
y = -6, perpendicular
Step-by-step explanation:
You can use the points to find the slope of the line:
Then, using point-slope form, choose one set of coordinates to use for y1 and x1:
Since the slope of the line is zero, it's a horizontal line. The y-axis is a vertical line, which means that the line is perpendicular to the y-axis.
They bought 8 orchestra seats and 6 mezzanine seats.
Step-by-step explanation:
Cost of one orchestra seat = $42
Cost of one mezzanine seat = $25
No. of people = 14
Amount spent = $486
Let,
x be the number of orchestra seats
y be the number of mezzanine seats
According to given statement;
x+y=14 Eqn 1
42x+25y=486 Eqn 2
Multiplying Eqn 1 by 25;
Subtracting Eqn 3 from Eqn 2 to eliminate y;
Dividing both sides by 17
Putting x=8 in Eqn 1
They bought 8 orchestra seats and 6 mezzanine seats.
