Which image is a reflection of the black polygon in quadrant I? On a coordinate plane, the black polygon is reflected across the y-axis to form the red polygon.
the black polygon in quadrant I
the red polygon in quadrant II
the blue polygon in quadrant III
the green polygon in quadrant IV

the red polygon in quadrant ll

Step-by-step explanation:

I suppose that if the black polygon in quadrant l is reflected across the y axis it would land on quadrant ll.

B

Step-by-step explanation:

2 over 5

step-by-step explanation:

the 2: 3 ratio is the length of the ac segment to the cb segment total length. this implies that the ratio between segment ac length and segment ab length is 2: 5. point c is 2/5 from a to b, so the required fraction is 2/5.

answer:   rotate 270° clockwise about (7, 1) and reflect across the line x = 7
