Select all that apply. a point is reflected over the y-axis and translated up 3 units. how will the coordinates change? the x-coordinate will decrease by 3. the x-coordinate's sign will change. the y-coordinate's sign will change. the y-coordinate will increase by 3.

Step-by-step explanation:

If the point is translated across the y axis then the x coordinate will change sign.

If the point is translated upwards then the y coordinate will increase by 3

So the answers are B and D.

the answer is b. 60. each interior angle in 120, so the exterior angle must be 60 in order to add up to 180
