I'm very confused how to answer question 5, since there is no time value given.

300 250 200 Mean Ocean Levels (mm 150 y = 246.57x - 3358.7 100 50 0 13.6 13.8 14 Mean Global emperatures 2. What is the slope of this line? What does it represent? 244. 57 3. Using the model equation, predict the mean ocean level (mm) if mean global temperatures were to reach 16.C. 584. 42 mm 4. Using the model equation, predict the mean ocean level (mm) if mean global temperatures were to reach 20C. 1572. 7 mm 5. Describe how you might go about determining when (what years) we could expect to see the mean ocean levels you predicted in question 2 and 3 (50 - 100 words)
