Are the given lines perpendicular? y=-3, y = 2

no they are parallel the negative just means the y intercept is - 3

The lines are parallel not perpendicular

Step-by-step explanation:

Remember y = mx + b where m is the slope

y = - 3 is a horizontal line. The slope is 0

y = 2 is a horizontal line. The slope is 0

Both lines have the same slope, so they are parallel.
