a. The location of point A is described as (7,5). Use paper to locate and label point A on the coordinate plane. b. Use paper to reflect point A over an axis so its image is in Quadrant II. Label the image B. The ordered pair of point B is ( ).

Respuesta :

The solution:

Given the point A = (7,5)

We are required to find the coordinate of point B, where point B is the reflection of point A over the x-axis.

Note:

When you reflect a point across the x-axis, the x-coordinate remains the same, but the y-coordinate is taken to be the additive inverse. That is,

[tex]A(x,y)=B(x,-y)[/tex]

So, in this case,

[tex]A(7,5)=B(7,-5)[/tex]

Therefore, the correct answer is B(7,-5)
