On the first on it is the first answer and the last one.
second: the second and the third one.
It must be ≤ instead of ≥.
y ≤ - 3·x + 4
Too long busy make it shorter
Kilograms is probably the best answer.
Given:
The equations are


To find:
Which function is changing more quickly.
Solution:
The slope intercept form of a line is

Where m is slope and b is y-intercept.
On comparing
with the slope intercept form, we get



On comparing
with the slope intercept form, we get


Since,
, it means the absolute rate of change of second function is greater than the first function.
Therefore, the second function is changing more quickly.
