Which algebraic rule for a rotation describes the change in coordinates: G(5, -1) to G' (-5, 1)?

Rotate 180 degrees around (0,0) or flip y axis and then x axis

1) 2/5

2) zero=0/1

3) zero=0/2

4) -4/5

5) undefined=3/0

y= 2x+7

changed to y= 5x +7

as slope is increased from 2 to 5

therefore it would be less steeper

so, option d) is correct
