Help me with this please

(2,1)

Step-by-step explanation:

basically just subract them by eachother

Step-by-step explanation:

kx then is 5 = (x1 + 3) / 2

10 =x1 + 3

7 = x1

ky then is 3 = (y1+2)/2

6 = y1+2

4=y1

K=(7,4)

step-by-step explanation:

y = | -2(-2) |     →     y = | 4 |     →     y = 4       ⇒   (-2, 4)

y = | -2(-1) |     →     y = | 2 |     →       y =   2       ⇒   (-1, 2)    

y = | -2(0) |     →     y = | 0 |     →       y = 0         ⇒   (0, 0)

y = | -2(1) |   c →     y = | -2 |     →     y =   2         ⇒   (1, 2)    

y = | -2(2) |     →     y = | - 4 |     →     y =   4         ⇒   (2, 4)
