Question 83717: Hi! I have a question on how to work this problem. I know what the answer would be if they said what temperature would it be after 3 hours, but I do not even know what a linear relationship is.
The problem: Write a linear relationship that describes the out side temperature, T, as a function of the number of hours since 8:00am., h. At 8:00am the outside temperature was 76(degrees)F and each hour the temperature rose 3 degrees.
Thanks for your help,
Melissa

You can put this solution on YOUR website! Write a linear relationship that describes the outside temperature, T, as a function of the number of hours since 8:00am., h. At 8:00am the outside temperature was 76(degrees)F and each hour the temperature rose 3 degrees.
--------------------
T(h) = 3(h-8) + 76
This means "The termperature h hours after 8:00 is 3 times the number
of hours + 76".
-------------------
A linear relationship is one that can be written in the form y = mx+b
where m is the slope and b is the y-intercept of the graph of the equation.

You can put this solution on YOUR website! t=76+3h where t=current temperature after 8:00am. h=the number of hours since 8:00am.
example: at 12:00 the temperature would be:
t=76+3*4
t=76+12
t=88 degrees.
