W = 17/13.
I hope this helps. I'm pretty sure I got it wrong, but just let me know.
Using linear function concepts, the graph of the Celsius-Fahrenheit relationship is linear with an intercept of 32 and slope of 1.8.
<h3>What is a linear function?</h3>
A linear function is modeled by:
y = mx + b
In which:
- m is the slope, which is the rate of change, that is, by how much y changes when x changes by 1.
- b is the y-intercept, which is the value of y when x = 0, and can also be interpreted as the initial value of the function.
From the table, we have that:
- When the input is of 0, the output is of 32, hence the intercept is of 32.
- When the input changes by 10, the output changes by 18, hence the slope is of 18/10 = 1.8.
Thus, the graph of the Celsius-Fahrenheit relationship is linear with an intercept of 32 and slope of 1.8.

#SPJ1
Y = kx
so
k = y/x
<span>y is 20 when x is 4
k = 20/4 = 5
Answer
The </span><span>constant of variation for the relation = 5</span>
-3.3 + 5.5 is the same as 5.5 - 3.3 so the answer is 2.2
