Ineed with these questions . they are uploaded. type what number you are doing !

6. positive linear
7. both calculated the slope as 2/3
8. slope = (145 - 190) / (1 - 0) = -45rate of change(slope) = -45 per month
10. (0,60)(1,90)...slope = (90 - 60) / (1 - 0) = 30
     y = mx + b
     slope(m) = 30
     (0,60)...x = 0 and y = 60
      60 = 30(0) + b
      60 = b
      equation is : y = 30x + 60...fixed amount is 60

Num of plants = (original#ofplants)*(1.6)^t
