Answer:
Number 3 would be considered a constant.
Step-by-step explanation:
7h and an h at the end, so it isn't a constant number.
It would be: 15/7 = 2 1/7
You have two points
(12,2200) and (10,3000) You have enough information to set up an equation.
x1 = 12
x2 = 10
y1 = 2200
y2 = 3000
The slope = (y2 - y1)/ (x2 - x1)
The slope = (3000 - 2200) / (10 - 12)
Slope = 800 / - 2
slope = - 400
So far what you have is y = - 400x + b
To get b just use one of the points.
(10,3000)
y = - 400x + b
3000 = -400*10 + b
3000 = - 4000 + b Add 4000 to both sides.
3000 + 4000 = b
b = 7000
Answer y = - 400x + 7000
What happens if you use (12,2200)
y = -400*12+ 7000
y = - 4800 + 7000
y = 2200 As it should.
