Answer:
The average is 1550
Step-by-step explanation:
idk how to do this i just looked up an average calculator
Decimal form: -2.6666..
Fraction form: -2 2/3
10y - 5x = 40 Add 5x to both sides
10y = 5x + 40 Divide both sides by 10
y =

x + 4
The
y-intercept is 4 and the
slope of the line is 
.
You can find these by comparing your equation to the equation y = mx + b, where m is the slope of the line and b is the y-intercept.
Answer: y <= 2x+3 or 2x+3 >= y
Step-by-step explanation: Assuming each interval is one unit
