<h3>
Answer: Linear</h3>
Each time x goes up by 3, y goes up by 2. The rate of change is constant.
slope = (change in y)/(change in x) = 2/3
y intercept = 6 since this is where x = 0
The equation of this line is y = (2/3)x+6

Answer:
44.8 mph
Step-by-step explanation:
Betsy drove from london to wolverhampton.it took her 2.5 hours at an average speed of 56 miles per hour.Mac drove the same journy by motor bike.It took him 2 hours.Assuming that both took the same route,work out Mac's average speed in mph.
The above question is solved using Proportion method
2.5 hours = 56 mph
2 hours = x mph
Cross Multiply
2.5 hours × x mph = 2 hours × 56 mph
x mph = 2 hours × 56 mph/2.5 hours
x mph = 44.8 mph
Therefore, Mac's average speed = 44.8 mph
