In a lab a substance was cooled by 42C over a 7 hours at a constant rate. What was the change in temperature each hour?

1 answer:

4 0

The rate of change is -6c per hour.

42c/7=6.

I believe the rate of change is negative because the question states that the temperature is decreasing.

Answer:

As "x" increases "y" *decreases*

y as a function of x is not *constant*

Therefore the function is *nonlinear*

For all values of x, the function value y *≥* 0.

The y intercept of the graph is *8*

x=1 function value of y is *5*

Y= mx+b (slope intercept form)
m= the slope (in this case 8)
b= the y-intercept (-3)
the answer: y=8x-3
