The point (1, –5) is reflected across the y-axis. What are its new coordinates? (–1, 5) (1, –5) (–1, –5) (1, 5)

(- 1, - 5 )

Step-by-step explanation:

Under a reflection in the y- axis

a point (x, y ) → (- x, y ), thus

(1, - 5 ) → (- 1, - 5 )

(-1,-5)

Step-by-step explanation:

10 cm

step-by-step explanation:

if the polygon is a rectangle, then the perimeter is x+x+y+y. using the values that you gave, the perimeter is 3+3+2+2=10cm.

answer: 10 meter
