Question

Transform the coordinates of point M to reflect the point across the x-axis?

Answer 1

When you transform a coordinate by reflecting across the x-axis, only the y-coordinate will be transformed from positive to negative and vice versa

`\text{ Reflected along x-axis: M(x,y) }\rightarrow\text{ M'(x,-y)}`

For the given point: (-4,-8)

The transformed coordinates when reflected along the x-axis will be,

`\text{M(x,y) }\rightarrow\text{ M'(x,-y)}`
`\text{M(-4,-8) }\rightarrow\text{ M'(-4,-(-8))}`
`\text{M(-4,-8) }\rightarrow\text{ M'(-4,8)}`

Therefore, M' = (-4,8).
