Answer:
(17,21)
Step-by-step explanation:
Note that if a coordinate point is reflected over the x axis, the y axis of the coordinate will be negated while the x coordinate is unchanged.
For example, if a coordinate (x,y) is reflected over the x axis, the resulting coordinate of the reflected point will be (x, -y)
Note that the y coordinate was negated.
Applying this to the question
Given the coordinate point (17, -21). If reflected over the x axis, the coordinate of the reflected point will be (17, -(-21)) which will be (17,21)
