Q:

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

Accepted Solution

A:
Answer:The answer to your question is:  x = -1Step-by-step explanation:Dataslope of l = xslope of m = x +2they are ⊥ProcessIf 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
