Question

Laura puts a casserole into the freezer. She noticed that after 10 minutes, the temperature of the casserole was 76 degrees.

After 25 minutes, the temperature was 70 degrees. Laura writes a linear equation to model the temperature change.

Which of the following shows the temperature, y, after x minutes?
