Can someone with this question idk how to do it

Both are located on railroad lines

the question asks for similarities between Denver and Cheyenne. If you look at the map, both have the dotted line along them. In the key, the dotted lines represent railroads.

the answer is 5636.7

the slope of the line is 60

one point on the line is (40,10)

step-by-step explanation:

in the equation outside the parenthesis the equation always tells you the slope. in this case it is 60.

in the parenthesis is also says 40 which is x because it is near the x and 10 is y because it is near y.
