In a coordinate plane, Brittany labeled the coordinates for point m as (-31/2,2). Sade tells Brittany to reflect point m over the x axis to point r. What are the coordinate of point r?
To reflect a point over the x-axis, we need to keep the y-coordinate the same and change the sign of the x-coordinate.
In this case, the coordinates of point M are (-31/2, 2). To reflect it over the x-axis to point R, we keep the y-coordinate of R the same, which is 2.
Then, we change the sign of the x-coordinate of M, which means we change the negative sign to positive. Therefore, the x-coordinate of point R becomes 31/2.
Thus, the coordinates of point R are (31/2, 2).
