If (2,3) is reflected over the y axis what is the new coordinates

Andrei [34K]

Answer:

(-2,3)

Step-by-step explanation:

When you reflect a point across the y-axis, the y-coordinate remains the same, but the x-coordinate is transformed into its opposite (its sign is changed). Notice that B is 5 horizontal units to the right of the y-axis, and B' is 5 horizontal units to the left of the y-axis. the y-axis is the point (-x,y).

1. 5/6 = 10/12

3/4 = 6/8

2. 2/9 = 4/18

4/12 = 1/3

3. 6/7 = 12/14

1/2 = 2/4

4. 5/9 = 10/18

3/18 = 1/6

5. 1/6 = 2/12

1/9 = 2/18

6. 3/8 = 6/12

5/6 = 10/12

X+(x+2)+(x+4)+(x+6)=4x+12=212

Mrac [35]

(x+(x+2)+(x+4)+(x+6))=4x+12=212

x+x+x+x(2+4+6)=4x+12=212

4x (2+4+6)=4x+12=212

4x(6+6)=4x+12=212

12+4x=4x+12=212

-12 -12 -12

4x=4x=200
