At the start of an experiment, the temperature was 15C. After 5 minutes, the temperature was 30C.

Write an equation in slope-intercept form to represent the increase in temperatures. What is the rate of change of temperature to minutes?

The equation in slope-intercept form is y = 5x + 15, where y is the temperature and x is the number of minutes.

The rate of change of temperature to minutes is 5°C/min.
