indicate whether the lines are parallel, perpendicular, or neither justify your answer.
x=-1 and y=-1

lines are perpendicular

Step-by-step explanation:

The equation of a vertical line parallel to the y- axis is

x = c

Where c is the value of the x- coordinates the line passes through

x = - 1 ← is the equation of a vertical line

The equation of a horizontal line parallel to the x- axis is

y = c

Where c is the value of the y- coordinates the line passes through

y = - 1 ← is a horizontal line

Since lines are vertical and horizontal they are perpendicular to each other.
