A contractor is building a new subdivision on the outside of a city. He has started work on the first street and is planning for the other streets to run in a direction parallel to the first. The second street will pass through (1, 5). Find the equation of the location of the second street in standard form. Coordinate grid with a segment labeled street 1 that extends between the points negative 5 comma 6 and three comma negative 2; a point labeled street 2 is at 1 comma 5 x + y = 6 2x + y = 7 x − y = 6 2x − y = 7.
