True or false. if two lines are perpendicular, their slopes are negative reciprocals.

True

Step-by-step explanation:

Let there be two perpendicular lines AB and CD having slope m₁ and m₂.

Now, we know that,

When two lines are perpendicular, the product of their slopes is -1.

Thus, we get that the product of m₁ and m₂ is -1.

i.e. m₁ × m₂ = -1

i.e.

i.e. m₁ is negative reciprocal of m₂.

Thus, the slope of line AB is negative reciprocal of the slope of line CD.

Hence, the given statement is true.

step-by-step explanation:

its that because if it was in the pm it would be 1345

your answer would be 10x - 1
