Step-by-step explanation:
so basically for this on u have to draw this on graph every first number of the coordinate is on x axis e.g . (7,0) 7 is on x axis and 0 is on Y axis. you can use tracing paper for this which will be more helpful as u can trace the shape and move it half way.
As u rotate it around the origin so u just turn it half way. eg I drawn it on the picture.
hope this make sense :)
