Question

The slopes of lines PQ and P’Q’ can be determined using the formula The product of these slopes is ________. This product shows that the slopes are negative reciprocals. It is given that the lines are perpendicular and we have shown that the slopes of the lines are negative reciprocals.

Answer 1

Explanation:

Answer 2

we know that

If two lines are perpendicular. then the product of their slopes is equal to -1 because the slopes are negative reciprocal

so

m1*m2=-1

m1=-1/m2

therefore

the answer is

The product of these slopes is -1
