The step by step explanation is as shown in the attachment.
Basically, what was applied is the knowledge of differentiation and integration.
Answer:
7 pounds and 1.4763 ounces
Using the two coordinates you can find the equation
------------------------------------
Find slope first
Slope

0 - 3 = -3
-------
-4 - 0 = -4
--------------------------------------------------
Simplify -3/-4
3/4
-----------------------------------------------------------
Your slope is 3/4 and the Y-intercept as mentioned in the question is "3"
----------------------------------------------------------------------
So your equation is y = 3/4x + 3
