Answer : D
From the given graph,
x represents the ounces of salad dressing
y represents the total number of calories
From the graph , y intercept is 50
Now we find slope using any two points from the graph
Pick any two points
(0.5,100) (1.5,200)
[tex]slope = \frac{y_2-y_1}{x_2-x_1} =\frac{200-100}{1.5-0.5} =100[/tex]
slope = 100 that is 100 calories per ounce
y intercept = 50 that means 50 calories topped
So, answer is the total number of calories, y, in a salad with vegetables containing 50 calories topped with x ounces of salad dressing at 100 calories per ounce
