What would be perpendicular to the like y = - 2

Perpendicular lines are two lines that form two 90 degree angles. Since y = - 2 is a horizontal line, any line written as, for example, x = - 2 or x = 20 would be perpendicular. This is because if you only set x equal to a value, it creates a vertical line.

Step-by-step explanation:

eq. of any line ⊥ to y=-2 is

x=k, where k is a real number.

it may be y-axis or any line ║ to y-axis.
