The sequence of transformations, RO,90° ° Tx-axis, is applied to ΔXYZ to produce ΔX''Y''Z''. If the coordinates of Y'' are (3, 0), what are the coordinates of Y? Y(_,_)
Accepted Solution
A:
A rotation 90 can be represented by the formula (x,y)—>(-y,x)
(3,0)
3 is the x point. 0 is the y point. Replace these two points (swap them)
