Question

On a coordinate plane, a triangle has points A prime (6, 8), B prime (10, negative 6), and C prime (6, negative 6). What is the pre-image of vertex A' if the image shown on the graph was created by a reflection across the y-axis? (–8, –6) (–6, 8) (8, 6) (6, –8)

Answer 1

Answer:

I would say D.) (6,-8)

Step-by-step explanation:

I say this because we're reflecting the point across the y-axis and if the y-axis is positive then the y-axis on the other number would be negative and we know that ordered pairs go like (x-axis, y-axis) and we know that that A prime is (6,8) so the ordered pair that hasn't been reflected would go like (6,-8)

(sorry if it doesn't make that much sense but I hope I helped you out some:))
