Suppose a coordinate plan were transposed over the map of a city, and First Street had the equation y=2x+1. If the Second Street ran parallel to First Street, and it passed through the points (5,9), what would be the equation of Broad Street?

d. 8

step-by-step explanation:

the given radical expression is:

we can rewrite this as:

we express as square numbers to get;

the exponents will now cancel out to give.

the correct answer is d

for this case we have by definition, if two lines are perpendicular, then the product of their slopes is -1.

then, given the following line:

so,

we are looking for m_ {2}:

then, the line is given by:

we find "b" replacing the given point:

finally, the equation is:

option c

i believe that the answer is

b. y-1=-2(x-4)

hope this !
