Question

I need help with geometry homework​

Answer 1

A. This is a what YOU think... how do YOU see it. to me, it looks like it lays down on its left side ... it spun to the left or rotated 90 degrees to the left (of course it could have rotated 270 degrees to the right)
B. Good job
C. Look at your answers in part B. (Ignore the third one until you think you have it. ). What happens? X goes to y and y goes to x? So the rule is (x,y) —> ( y, x)? No. The y changes signs... so ( -y, x)
D. What we just said in words in part C: the x & y switch places and the y changes signs. More “math-ey” sounding: the variables reverse and the y is multiplied by -1
