The situation shows two variables;
The number of days in the month (x variable) and the number of tree toppers made per day (y variable).
The Bumble can make 43 tree toppers every hour. If he works for 12 hours daily, that means he can make
Per day = 43 x 12
per day = 516 tree toppers
This means for the second day, he would have made, 516 x 2 = 1032 tree toppers. The equation to depict is derived as follows;
![\begin{gathered} y=mx+b \\ \text{Identify two points as} \\ A(1,516),B(2,1032) \\ m=(y2-y1)/(x2-x1) \\ m=(1032-516)/(2-1) \\ m=(516)/(1) \\ m=516 \\ \text{Inputing the values of x and y into the equation, we now have b as;} \\ y=mx+b \\ 516=516(1)+b \\ 516=516+b \\ 516-516=b \\ b=0 \\ \text{Hence, the equation is shown as;} \\ y=mx+b \\ y=516x+0 \\ y=516x \end{gathered}]()
This means for every value of x (that is for every subsequent day after december 1st), the value of y (number of tree toppers) can be derived from the equation shown above. Hence, we can write out an ordered pair as follows;
In the same manner we can now write out the entire ordered pair from December 1 to december 24, and then the graph can be drawn as shown below;
