Answer 1

sorry no clue either

Answer 2

:(

Answer 3

i am going to make a guess at A \(<-4,9>\)

Answer 4

think of moving the point \(T\) to the origin
that would move it left 2 and up 5

Answer 5

guess i meant "up 4"

Answer 6

To get from S to T, you go left 4, and up 9

left 4 means -4 is the x-value
up 9 means +9 is the y-value

Answer 7

Two ways to look at it


A) you start at (2,-4) and you need to get to (-2,5). So you go 4 units to the left and 9 units up. This is represented by the vector <-4,9>


B) subtract the corresponding components (tail - head) to get
x: -2-2 = -4
y: 5 - (-4) = 9
so again, we get the vector <-4, 9>

Answer 8

lol no
