A large western state consists of 2913 million acres of land Approximately 61% of this land is federally owned. Find the number of acres that are not federally owned

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
