Point [tex] B [/tex] has coordinates [tex] (-3,-8) [/tex], while point [tex] D [/tex] has coordinates [tex] (4,-6) [/tex].
So, to go from [tex] B [/tex] to [tex] D [/tex] the [tex] x [/tex] coordinate must go from [tex] -3 [/tex] to [tex] 4 [/tex], while the [tex] y [/tex] coordinate must go from [tex] -8 [/tex] to [tex] 6 [/tex]. This means that the [tex] x [/tex] coordinate must grow [tex] 7 [/tex] units, while the [tex] y [/tex] coordinate must grow [tex] 2 [/tex] units.
So, the answer is the last one.
