Answer
Option C is correct.
Profit increases by 0.5 dollars per glass sold.
Explanation
The slope and y-intercept form of the equation of a straight line is given as
y = mx + c
where
y = y-coordinate of a point on the line.
m = slope of the line.
x = x-coordinate of the point on the line whose y-coordinate is y.
c = y-intercept of the line.
So, in P = 0.5G - 4,
Slope = 0.5dollars per glass sold.
Hope this Helps!!!
