Question

The Reflection of the point across X axis for the ordered pair B ( -4 , -2 1/2 ) B( 4, 2 1/2) B( -4 , 2 1/2) B( -4 , -2 1/2)

Answer 1

`\sf(-4 , 2(1)/(2))`

Explanation:

Reflection:

Reflection of a point (x, y) across x-axis is (x, -y)

`\sf Point \ B(-4, -2(1)/(2))`

Reflection of a point across x-axis is,
`\sf B(-4, 2(1)/(2))`
