Question 144322: his is another WORD PROBLEM that i do not understand how to do, can someone please help?
2. You are trying to decide how to most efficiently use your oven. You do not want the oven running at a high temperature when it is not baking, but you also do not want to waste a lot of time waiting for the oven to reach the desired baking temperature.
The instruction manual on the industrial oven suggests your oven temperature will increase by 45 degrees Fahrenheit per minute. When the over is initially turned on, the temperature is 70 degrees Fahrenheit. What will the temperature of the oven be after 7 minutes? Write an expression and explain how you arrived at your answer.

Temp = initialTemp + 45*t
The initial temp is 70. every minute the oven is on, it can increase its temperature by 45 degrees. Let t be the number of minutes the oven is on. then the Oven temperature = 70 + 45t

--------------
You have two points relating time and temperature:
(0,70) and (1,70+45)
-----------------------
Find the equation:
slope = 45
intercept = 70
-----------
EQUATION:
t(x) = 45x + 70 where x is the number of minutes and t is temperature
t(7) = 45*7+70 = 385 degrees
