Answer:
b. both functions have a negative slope
Step-by-step explanation:
The given function is
![f(x)=-6x-21](https://tex.z-dn.net/?f=f%28x%29%3D-6x-21)
This function is of the form
, where
is the slope and
is the y-intercept.
We can also determine the slope of the function in the table using any two points, say
.
The slope formula is given by,
.
If
, then,
![m=\frac{6-7}{2-0}](https://tex.z-dn.net/?f=m%3D%5Cfrac%7B6-7%7D%7B2-0%7D)
.
We can see that both functions have a negative slope.
The correct answer is B.
