Answer:
-1/3
Step-by-step explanation:
Use the formula, (y2 - y1)/(x2 - x1). In this case, there is a negative slope.
Start from point, (1, 9) and go to point (4, 8).
Use the formula:
(y2 - y1)/(x2 - x1)
Y2 = 8
Y1 = 4
X2 = 9
X1 = 1
(8 - 9)/(4 - 1) = -1/3
Therefore, the slope is -1/3

Answer:
The number of miles her car travel per gallon of gas is 38 miles per 1 gallon of gas
Step-by-step explanation:
Given
Size of Gas = 12 gallon of gas
Distance = 456 miles
Calculating the number of miles her car travel per gallon of gas.
This in calculated by distance/size of gas
By substituton, it becomes
Number of miles = 456 miles/12 gallons ------ divide
Number of miles = 38 miles / gallon.
Hence, the number of miles her car travel per gallon of gas is 38 miles per 1 gallon of gas
