SOLUTION

Given the image

For statement 1

The coordinate of point A after a clockwise rotation of 90° about the origin is (3,-1)

Note that a clockwise rotation of 90° is defined as


(x,y)\Rightarrow(y,-x)

From the image, the coordinate of point A is (1,3)

Therefore the statement is TRUE

STATEMENT 2

The coordinate of Point A after dilation of the scale factor of 2 is (2, 6)

For a dilation of the scale factor of 2, the coordinate will be doubled

Therefore the statement is TRUE

The next two statements are FALSE
