Which statement explains how you could use coordinate geometry to prove the diagonals of a quadrilateral are perpendicular ?

b- use the slope formula to prove the slopes of the diagonals are opposite reciprocals

Step-by-step explanation: I searched it up and well, cause the slope of the diagonals are the same but to prove you have to measure the shape and prove the diagonals .

2 is the final ! : )

7! = 7×6×5×4×3×2

3! = 3× 2

as 7! is multiple of 3! because 7! contains 3! that is 3× 2 as factor

so 7! /(3! ) = 7× 6× 5× 4

= 42 × 20

= 840

its b) 840✌✌✌
