Respuesta :

I think the answer is B

Perpendicular lines were defined as two different lines meeting at a straight angle, or 90°. Since two lines intersect at right angles, the word "perpendicular" means "at right angles".

Perpendicular line:

  • Perpendicular lines could be drawn in any direction, including up and down, across, and sideways.
  • First, we find the slope of lines m and n. Since we know that two lines are perpendicular, the product of their slopes is equal to -1.
  • Slope m [tex]\times[/tex] Slope n [tex]=-1[/tex]
  • Slope m =[tex]-1 \div[/tex] Slope n

Therefore, the final answer is "Option C".
