Tell whether the lines through the given points are parallel, perpendicular, or neither.
Line 1: (-9,3), (-5,7)
Line 2: (-11, 6), (-7, 2)
The slope of line 1 is
The slope of line 2 is
The two lines are

Respuesta :

Answer:

The slope of line 1 is: (7-3) / (-5 - -9) = 4/4 = 1

The slope of line 2 is: (2-6) / (-7 - -11) = -4/4 = -1

Yes, they are perpendicular

Step-by-step explanation:

The slope of line 1 is: (7-3) / (-5 - -9) = 4/4 = 1

The slope of line 2 is: (2-6) / (-7 - -11) = -4/4 = -1

slope 2 = - 1/1 = - 1/slope 1
