This blog is an interactive math classroom where my students will be engaged in answering questions pertaining to my lessons and post comments about other students' comments. This blog will serve as an online learning experience for my self and my students. Parents are also encouraged to participate by providing reflective comments about this blog.

What is the rule for reflecting a geometric shape in the x-axis? In the y-axis?
For reflecting a geometric shape in the x-axis you change the y to it's opposite. When reflecting in the y-axis you change the x to it's opposite . For exampe , ( x , y ) - - > ( - x , y ) ( x , y ) - - > ( x , - y )
when reflecting of the x axis, the y value becomes negative (x, y) -> (x, -y) when reflecting of the y axis, the x value becomes negative (x, y) -> (-x, y)
In x axis the y changes into its opposite and in the y axis the x changes into its opposite to
ReplyDelete(x,y)-->(x,-y) in x axis
(x,y)-->(-x,y) in y axis

ReplyDelete(x, y) -> (x, -y)
when reflecting of the y axis, the x value becomes negative
(x, y) -> (-x, y)
reflecting in the y axis the x becomes negative and when reflecting in the x axis the y value becomes negative
ReplyDelete(x,y)->(-x,y)
(x,y)=>(x,-y)
