3 Rectangle ABCD is dilated by a scale factor of 2 with the origin as the center of dilation, resulting in the image A'BCD. If the slope of AB -2, what is the slope of A' B'?
OA. .-4
OB. -1
OC -2
OD. 0

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✌✌✌
