Question

Determine which two equations represent perpendicular lines.
(a) y = x – 2 (b) y = 2x – (c) y = x + (d) y = x –

Answer 1

Isn't this YOUR homework?

Answer 2

If two lines are pependicular, they have negative reciprocal slopes. For example, y = 3*x is perpendicular to y = (-1/3)*x. Unfortunately, I think you have mistyped your problem, as no two of those choices are perpendicular to each other.

Unless you meant to write y = x and y = -x for choices c) and d). Then choices a) and c) would both be perpendicular to choice d).

Answer 3

not one of the equations characterize perpindicular line, because you should have one equation with an complete huge form in the front of the x, and the different equation with the adverse reciprocal of the full huge form in the front of the x.
