A y=3x because 3*1 is 3 and 3*2 is 6 and so on
Answer:2
Step-by-step explanation:
Going 315 km uses up 35 liters of gasoline
On average, 1 liter of gasoline can travel the number of kilometers:
315 : 35 = 9 liters of gasoline
The addition of +7 influences the y values of the graph. Since it is positive, the graph of y=IxI would be moved 7 units upwards.
