Answer:
2
Step-by-step explanation:
To find the slope, we use the equation
m = (y2-y1)/(x2-x1)
Since the have the points (2,-4) and (4,0)
m = (0--4)/ (4-2)
= (0+4)/(4-2)
= 4/2

Answer:
12 cm = 21.62 miles
6 cm = 11.04 miles
Step-by-step explanation:
To find the distance, set up a proportion. A proportion is two equal ratios set equal to each other. We form the ratios by using corresponding values. We write a ratio of 
and simplify.
We know 
. We know the distance on the map is 12 cm and 6 cm whish converts to 4.7 inches and 2.4 inches. We can write 
and 
We set them equal.
and
To solve each proportion, we'll cross multiply by multiplying numerator with denominator across the equal sign.
