Answer:
y = 392x + 6350
Step-by-step explanation:
Here, we calculate the average rate of change in the number of muffins sold between the two years
Mathematically that will be the difference in number of muffins divided by the number of years
We have this as;
(8310-6350)/(2015-2010)
= 392
an average of 392 muffins were sold in a year
The general form of the equation of a straight line is;
y = mx + c
we have m as 392
so;
y = 392x + c
To get c, we make a substitution
2015 is 5 years after 2010, so x will be 5 and y will still be 8310
so;
8310 = 392(5) + c
c = 8310 - 2960
c = 6350
So the equation is;
y = 392x + 6350
