Question

The vertices of a rectangle are A (1,-1), B (3,-1), C(3,-2) and D(1,-2). If the rectangle is dilated by a scale factor of 2. the image coordinates would be A(-2,2), B(-2,6), C(-4,6), D(-4,2) A(2,-2), B(6,-2). C(6.-4). D(2-4) A(2.2), B(6,2), C(6,-4), D(2.4) A(4,2). B(2,4). C(3,-2) D(2-4)

Answer 1

A (1,-1)

B (3,-1)

C(3,-2)

D (1,-2)

To calculate the image coordinates, multiply each coordinate (x,y) by the scale factor (2)

A = (1*2, -1*2 ) = (2,-2 )

B = (6,-2)

C= (6,-4)

D = (2,-4)
