As part of a screening process, computer chips must be operated in an oven at 145 °C. At the end of the cycle, the oven must be cooled before the boards can be removed. Ten minutes after starting cool-down, the temperature is 66 °C. After 15 minutes, the temperature is 26.5 °C.
Write a function in slope-intercept form that describes the temperature in degrees Celsius, y, after x minutes of cooling.
