The slope of a line is -3. find the slope of a line that is perpendicular to this line. a.-3 b.-1/3 c.1/3

The slope of a line is -3
perpendicular  lines, slope is opposite and reciprocal
so the slope of a line that is perpendicular to this line will be 1/3

answer
C.1/3

Rounding  means we are finding the closest  benchmark number. abenchmark number  is one that is easy to  use  in operations and/or quicker to say and write. a  number  line can us  round  by showing the closestbenchmark number. five is the midpoint  between  0 and 10.
