It is estimated that 10% of all U. S. citizens have never traveled outside of the state in which they were born. If this is true, and two U. S. citizens were to be selected at random, what are the chances that NEITHER person has traveled outside of their own birth state?

answer: -8.2562234e+13

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

combine all like terms then its just a 2 step equation
