Answer:
y=2 when x=2
Step-by-step explanation:
3(2)=6
6+6y=18
6y=18-6
6y = 12
6y/6 = 12/6
y=2
Answer:
Step-by-step explanation:
If the price is linear, then the slope between each pair of points must be the same.
m = Δy/Δx
m = (150 - 70) / (5 - 1) = 20
m = (450 - 150) / (20 - 5) = 20
m = (1050 - 450) / (50 - 20) = 20
So the equation is indeed linear. It has a slope of 20 and y-intercept of 50.
p = 20n + 50
