If the slope of line l is x, and the slope of line m is x+2, and l⊥ m, what is x?

The answer to your question is: x = - 1

Step-by-step explanation:

Data

slope of l = x

slope of m = x + 2

they are ⊥

Process

If they are ⊥, then, x + 2 = - 1/x

x (x + 2) = - 1

x² + 2x = - 1

x² + 2x + 1 = 0

(x + 1) ² = 0

x + 1 = 0

x = - 1
