From the given picture we can see a linear graph represents the relation between the number of gallons used in miles
The x-axis represents the number of miles
The y-axis represents the number of gallons
In the point (73.5, 3.5),
its x-coordinate (73.5) represents the number of miles
its y-coordinate (3.5) represents the number of gallons
Then the statement the care used 70 gallons to travel 3 miles is wrong
Because 70 should be the number of miles and 3 should be the number of gallons
The answer is the right statement (2nd) in the first row
