(1) The train travels 4 miles per gallon.
(2) The slope of the graph is 
Explanation:
(1) The miles that train travels per gallon is given by
Dividing, we have,
Thus, the train travels 4 miles per gallon.
(2) To determine the slope, let us consider two points from the graph.
The coordinates are 
and 
Thus, substituting the coordinates in the slope formula, we get,
Simplifying, we have,
Thus, the slope of the graph is
Answer:
0.8 or 80%
Step-by-step explanation:
To easily find percents, divide the numerator with the denominator. Or, first you can simplify the fraction first.
20/25 can be divided by 5. Which is 4/5.
4/5=0.8
So, the answer is 80%
