Question

The slope of a line that is perpendicular to another line, is the negative reciprocal. The negative reciprocal means that you flip the fraction and change the

sign

TRUE or FALSE

Answer 1

The correct answer is true

Answer 2

TRUE

Explanation:

There is a fact about the perpendicular lines:

The product of their slopes is -1

Example:

• If the slope of one line is
  `(2)/(3)`, then the slope of the line which is perpendicular to it is
  `(-3)/(2)` because
  `(2)/(3)` ×
  `(-3)/(2)` = -1

• 
  `(-3)/(2)` is the negative reciprocal of
  `(2)/(3)`

• To get the slope of a perpendicular line to a line flip the slope of the line and change its sign

The slope of a line that is perpendicular to another line, is the negative reciprocal is TRUE
