Given that lines c and d are perpendicular to each other, if line c has a slope of -4, therefore the slope of line d will be: B. 1/4
Recall:
- Negative reciprocal of a number, "-n" equals 1/n, conversely, negative reciprocal of 1/n = -n.
- The slopes of two lines that are perpendicular to each other are negative reciprocal of each other.
Therefore, given that lines c and d are perpendicular to each other, if line c has a slope of -4, therefore the slope of line d will be: B. 1/4
