Answer: C
Step-by-step explanation:
Looking at the graph, we can see that the y-intercept is 16. Know this, we can automatically eliminate A, B, and D. To be sure, we should also check to make sure C is our right answer.
To find the slope, we cna take any 2 points and fill in the equation [tex]m=\frac{y_{2}-y_{1} }{x_{2}-x_{1} }[/tex]. Let's use (8,0) and (6,4).
[tex]m=\frac{4-0}{6-8} =\frac{4}{-2} =-2[/tex]
In answer choice C, the slope is -2. Therefore, C is the correct answer.
