SOLUTION: A piece of metal is heated to 3000C and then placed in a cooling liquid at 500C. After 4 minutes, the metal has cooled to 1750C. Find its temperature after 12 minutes

Question 908856: A piece of metal is heated to 3000C and then placed in a cooling liquid at 500C. After 4 minutes, the metal has cooled to 1750C. Find its temperature after 12 minutes
Answer by josgarithmetic(39630) (Show Source): You can put this solution on YOUR website!
Identify two linear data points (x,y) using x for time after placement in the coolant and y for temperature.

(0,3000) and (4,1750).
ASSUMING a linear fit, find the line which contains those two points.
Most convenient is slope-intercept form because you already have "b", the y intercept.

Good method is fill as ;
simplify the equation.
