Question

Click the spot on the graph C' would-be located if the triangle was rotated 180 degrees clockwise

Answer 1

Assuming that the figure is rotated about the origin, a rotation of 180° is described by the rule:

$(x,y)\rightarrow(-x,-y)$

The coordinates of the point C are (4,7). Then, after a rotation of 180°:

$(4,7)\rightarrow(-4,-7)$

Therefore, the coordinates of C' would be:

$(-4,-7)$
