Question

What is the slope and are they linear/perpendicular? PHOTO ABOVE

Answer 1

Answer:

Slope of line 1 = 3

Slope of line 2 = 3

Slope of line 3 = -1/3

Line 1 and 2 are parallel

Line 1 and 3 are perpendicular

Line 2 and 3 are perpendicular

Step-by-step explanation:

Find the slope of each line by using this equation:

$y_{2} - y_{1} / x_{2} - x_{1}$

lines are parallel if they have the same slope and line are perpendicular in they have opposite reciprocal slopes. (-1/3 is the opposite reciprocal of 3).

Hope this helps!
