1. Change the equation 2x + 3y = 1,470 to slope-intercept form. Identify the slope and y-intercept of the equation. Be sure to show all your work. Slope intercept form:y=mx+c Slope (m) is:-2/3. Y-intercept (b) is:490 2. Describe how you would graph this line using the slope-intercept method. Be sure to write using complete sentences. (Hint: use your y-intercept and slope) 3. Write the equation in function notation. Explain what the graph of the function represents. Be sure to use complete sentences. (hint: function notation and slope intercept look alot alike. The only difference is slope intercept is y=mx+b and function notation is f(x) = mx+b)

the discoverers and explorers: 1. natives showed jedediah smith the way. 2. william sublette was the first cross it with a caravan. 3.joel walker and his family were the frist settlers to use it. the jumping off point: 1. founded in 1827 near where the missouri river flows into the mississippi. 2. by the 1840's, it was the most popular "jumping off" point for pioneers to stock their wagons with supplies. 3. missionaries from the church of jesus christ of latter day saints attempted to make independence their zion, or holy capital. the route west: 1. the first emigrants to oregon came by ship before the trail was established. 2. ships continued to to travel to oregon even after the overland migrations began, but they were not popular among the pioneers. 3. the fare for a sea journey to oregon was quite expensive--few pioneer families could afford it. i don't know the other three i'm sorry.

the underground railroad (apocope of the metropolitan railroad) is a system of urban trains located within a city and its metropolitan area. it is characterized for being a massive transport of passengers in the big cities, uniting diverse zones and their environs, with high capacity and frequency and in segregated form to other systems of transport. metropolitan railroads are built underground or on the surface, although most systems use mixed models where sections are combined in both modalities.

1 - as a result, the metro tends to reduce car travel for two reasons: first, due to the greater transfer of users from the car and, second, due to the reduction in the acquisition of cars in homes located in sectors near the stations of the metro.

2 -the metro allows to contribute effectively to the achievement of all the objectives of an urban development policy: it improves the efficiency of the city's economy by reducing travel costs and also generates a higher level of activities in the city center, taking advantage of of the agglomeration economies.

3 -it is a clean means of transport, since it uses renewable energy (usually electricity), taking care of the environment and avoiding excessive pollution.
