DX=-7
DX=-7Dy=4.5
DX=-7Dy=4.5Step-by-step explanation:
D=[1/3,2/4]
D=[1/3,2/4]=(4)-(8)
D=[1/3,2/4]=(4)-(8)=-4
D=[1/3,2/4]=(4)-(8)=-4DX=[2/4,-4/6]
D=[1/3,2/4]=(4)-(8)=-4DX=[2/4,-4/6]=12-(-16)
D=[1/3,2/4]=(4)-(8)=-4DX=[2/4,-4/6]=12-(-16)=12+16
D=[1/3,2/4]=(4)-(8)=-4DX=[2/4,-4/6]=12-(-16)=12+16=28

D=[1/3,2/4]=(4)-(8)=-4DX=[2/4,-4/6]=12-(-16)=12+16=28DY=[1/3,-4/6]=(1x6)-(-4x3)
D=[1/3,2/4]=(4)-(8)=-4DX=[2/4,-4/6]=12-(-16)=12+16=28DY=[1/3,-4/6]=(1x6)-(-4x3)=6+12
