In this case the temperature depends on the hour. So temperature is your X and hour is your Y variable. When h=0, x=0. So the 21*C is you x=0 or y-int point.
If we are trying to match the equation for a line of y=mx+b, 21*C=b.
Our rate of change is -4*C/h, which is our m variable.
So y=(-4)x+(21)
OR in this case, t=-4h+21.
Answer D.
ANSWER
The radius is 4
EXPLANATION
The given equation is:
We complete the square to get the expression in standard form:
We factor using perfect squares to get:
This implies that,
Comparing to
The radius is r=4
5/4 x 22/45
