Question

Texas predicted that the population would be about 17.4 million in 2018 and then increase by 0.22 million per year until 2020. Which linear equations models this situation?
A. y=17.4x +0.22
B. y= -0.22x + 17.4
C. y= 0.22x + 17.4
D. y= -17.4x + 0.22

Answer 1

Answer:

C. y = 0.22x + 17.4

Step-by-step explanation:

0.22x represents how much it's growing by. 17.4 represents the initial value.

y represents the final value.

Answer 2

Answer:

C. y= 0.22x + 17.4

Step-by-step explanation:

y= mx + b

0.22 million per year = m

17.4 = b

# of years = x

Total population = y

y= 0.22x + 17.4
