Shayla is tracking the weight of the smallest dog in a litter. use the table to write a linear function that models the puppy growth
week 0 weight in ounces 3
week 1 weight in ounces 6
week 2 weight in ounces 9
week 3 weight in ounces 12
a. y= 3x+3
b. y = 1/3x+3
c. y= 3x+12
d. y=1/3x+12

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.

a. -0.3 > -0.33

1. 22

2. 1

3. 7

4. 18
