create an equation that models the total number of calories Jonathan consumes y based on the number of biscuits he eats x and the packages of pemmican

93-8=85

855=17

17*4=68

there are 68 purple marbles in that bag

d will be the best answer

we need to see the graph to know but

strong positive is if it is going up from left to right in a straight diagonal line (like this /)

strong negative is the same but from right to left (like this \)

weak negative is the same as strong negative but its more straight line still right to left

and weak positive is the same as strong positive but more a straight line still left to right though.
