A
evaluate f(5) and f(2)
f(5) = 5m + b and f(2) = 2m + b, hence
f(5) - f(2) = 5m + b - 2m - b = 3m
the expression simplifies to
= 2 ( cross- multiply )
3m = 6 ( divide both sides by 3 )
m = 2 → A
1. To answer this question we must keep on mind that we already have the distance from Cleveland to Cincinnati.
2. They tell us that it is 40 centimeters on the first map.
3. If on the first map then:
4. Then the distance from Cleveland to Cincinnati is 400 kilometers.
5. On the second map
6. Then we want to know how many centimeters represents 400 kilometers on the second map. Therefore:
The answer is: 8 centimeters.
