The correct answer is B. The function has a constant rate of change, decreasing for all x at a rate of 6.
In order to find the rate of change, we have to identify the slope. The slope is always the coefficient of x when in slope intercept form. In this case it is -6, which means it decreases at a rate of 6.
The fast food restaurant sold 30 burgers with cheese and 21 burgers without cheese.
K/3 +21 = 27
subtract 21 from both sides...
k/3 = 48
now multiply 48 and 3 to find k...
48 x 3 = 144
k=144
