Answer:(0,0) (-1,0) (-1,3)

Step-by-step explanation:

scf 0.5 is shrinking the shape by a 1/2

The coordinates of a point of enlargment is (3,1)

so you work out the vectors of each corner than times it by 0.5

The vector of one cooridnate is (-6 -2)

-6x0.5=-3

-2x0.5=-1

so the vector is -3 -1 from the point of enlargment is the shape .

(-8 -2 ) is the coodinates of the next vector so

(-4 -1)

Then the last

(-8, 4)

(-4,2) vector for the last coodinate

sorry i couldn't write out the vector properly in the right notation .
