Answer:
y = 2x +7
Step-by-step explanation:
We are given two points on the growth curve: (weeks, ounces) = (2, 11) or (4, 15).
These can be used to write the equation of a line using the 2-point form:
y = (y2 -y1)/(x2 -1x)(x -x1) +y1
y = (15 -11)/(4 -2)(x -2) +11
y = 4/2(x -2) +11
y = 2x +7 . . . . . y = weight in ounces x weeks after birth

<em>Comment on the problem</em>
There are an infinite number of equations that can be written to go through the two given points. A linear equation is only one of them.
Answer:
Step-by-step explanation:
Given:
Number of feathers = 
Number of caps = 
Number of feathers in each cap = 3
Now, solving by setting up a proportion.
1 cap has 3 feathers. 'c' caps has 'f' feathers.
This gives,
Solving by cross multiplication, we get:
Therefore, the equation representing the number of feathers 'f' Erica needs to make 'c' caps is given as:
The answer is c
The rate of change is 30
