Answer:
B) Yes, because the slope is and the zero is (12, 0)
Step-by-step explanation:
From inspection of the graph:
- y-intercept = (0, 100)
- Two points: (3, 75) and (6, 50)
Therefore, the equation of the line in slope-intercept form y = mx + b
(where m is the slope and b is the y-intercept) is:
To find the zero (when y = 0), set the equation to zero and solve for x:
Therefore, the zero is at (12, 0)
Therefore, the graph does represent the function because the slope is and the zero is at (12, 0)
