line s has a slope of -9/5. line t has a slope of 5/9. are line s and line t parallel or perpendicular

Respuesta :

Answer:

perpendicular

Step-by-step explanation:

If 2 lines are parallel then their slopes are equal

If 2 lines are perpendicular then the product of their slopes = - 1

Here

- [tex]\frac{9}{5}[/tex] × [tex]\frac{5}{9}[/tex] = - 1

Then the 2 lines are perpendicular
