Answer:
Step-by-step explanation:
Generally, the single variable on the left side of the equation is the "output" or dependent variable, while any other variables on the right side of the equation are considered to be independent variables, or "input."
So, we assume your first question is asking for the value of t that makes w=176. Put the values in the equation and solve for the unknown.
w = 112 +8t
176 = 112 + 8t
64 = 8t . . . . . . . subtract 112
8 = t . . . . . . . . . divide by 8
The input for an output of 176 is 8.

Ordered pairs are always written as ...
(input, output)
So, (4, 144) means the output is 144 for an input of 4.
Answer:
-1
Step-by-step explanation:
Choose two point on that line such as (1,1) and (2,0)
Then use slope formula y-y/x-x
1-0/1-2 = 1/-1 = -1
