Okay for this question the answer is x=0.
Answer:
A
Step-by-step explanation:
For a linear function y = mx + b,
m is the slope and b is the y-intercept at x=0
From the given information, we can immediately see that at x=0 weeks, y = 3 oz, so b = 3
SO we can narrow down the correct answers to A and B where b=3
m can be found by applying the gradient formula m = (y2-y1) / (x2-x)
In this case, if we pick week zero and week 1,
x1=0, y1 = 3, x2=1, y2=6
m = (6-3) / (1-0) = 3/1 = 3
Hence A is the answer.
Step-by-step explanation:
Midpoint = 1/2(6+9,8+7)
= 1/2(15,15) = (15/2,15/2)
