additional points on the line. If x=1, then you add the slope to 15 to find y. 6.5+15=21.5 so the second point is (1,21.5). To find a third point, I had x=-1, so to find y, you subtract the slope from 15. 15-6.5=8.5 so the third point is (-1,8.5)
8. Using the coordinates from question 7, calculate the slope of your line. Does it match the slope from your model? ( 2 points )
Yes Graph the Equation 9. On the graph below, plot the points and sketch your line. ( 4 points: 1 for each graphed point, 1 for the line)
Find the Temperature Range 10. Complete the sentence for your layer. ( 1 point ) The troposphere is the region that starts at Earth's surface and ends between __8__ km and __20__ km above Earth.
The upper crust is the region that starts at Earth's surface and ends between _10___ km and _40___ km below Earth's surface. Use the temperature equation to find the temperature range for your layer. 11. What is the temperature at the end of your layer that is farthest from the surface? ( 1 point )
12. For the layer you selected, the temperature ranges from the temperature at Earth's surface, __6.5_____, to __15_____. ( 1 point )
