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 (−5, −1). 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 negative 5 comma negative 1
Since the slope is -x, you add x on both sides, resulting in the x+y. Since the y-intercept will be -6 (you can infer since the x-intercept is -6), x + y = −6 is the right answer.
