It would be the 2nd answer....your initial value (read from the left of the line graph) is 4.....following the line to the first even point you can see it has dropped 3 for the 4 points it has moved to the right....giving -3/4 as the rate of change.
1/8 + 1/6
= 1 x 3 + 1 x 4
——- ——
8 x 3 6 x 4
= 3/24 + 4/24
= 3 + 4
———-
24
= 7/24
(32 + 90 + 92 + 82 + 64 + x) / 6 = 85
(360 + x) / 6 = 85
360 + x = 85 * 6
360 + x = 510
x = 510 - 360
x = 150 <===
I think for the first one its always occur along plate boundaries, and for the second one its season of the year.
