W = 6t+90 represent the relationship between weight and number of months.
Step-by-step explanation:
Given,
Weight of wrestler = 90 kilograms
Weight after 8 months = 138 kilograms
Let,
x be the weight gained each month.
Weight of wrestler + Number of months*Weight gained each month = Weight after 8 months
Dividing both sides by 8
Therefore, the wrestler gained 6 kilograms each month.
W = weight of wrestler
t = number of months
Total weight = Weight before diet + Weight gain each month*Number of months
W = 90+6t
W = 6t+90
W = 6t+90 represent the relationship between weight and number of months.

Answer:
Step-by-step explanation:
How does y change as x increases over a range?
As x increases from -6 to -4, y decreases from 0 to -7
It is a decreasing function in this range and for ranges less than x = -6 as well as the slope is nearly constant
As x increases from -4 to 0, y increases from -7 to 4
It is an increasing function in this range.
For x increasing from zero, y becomes less and less
It is a decreasing function in the range larger than x = 0
