suppose a compact car uses 1 gallon of fuel for every 27 miles traveled. How would the graph for the compact car compare to the
graph for the car shown?
2 answers:
Answer:
1. The meaning of (2, 40) is that - when 2 gallons of fuel is used, then the distance covered will be 40 miles.
2. Equation will be :
where y is the total distance in miles and x is the number of gallons used.
3. When we have to tell as per graph, that the car travels 27 miles in 1 gallon, the points will be : (1,27) , (2,54) , (3,81) and so on.

Step-by-step explanation:
This problem can be done without the Distance Formula (which is a way to find the distance between any two points in the plane).
The attached image shows the points and segments joining them.
PQ = 5 because the points are on the same horizontal line, and you can count spaces between them (or subtract x-coordinates: 4 - (-1) = 5).
PR = 12 because the points are on the same vertical line; count spaces or subtract y-coordinates, 7 - (-5) = 12.
The triangle is a right triangle, so the Pythagorean Theorem can be used to find the length of the hypotenuse.
The perimeter of the triangle is 5 + 12 + 13 = 30
