This shows a set of axes with the scales marked from –3 to 3 on both the horizontal x-axis and the vertical y-axis. The axes intersect at the origin. Four points (E, F, G and H) are marked. E is opposite 1 on the x-axis and opposite 1 on the y-axis and is labelled E (1, 1). F is opposite minus 2 on the x-axis and opposite minus 1 on the y-axis and is labelled F (minus 2, minus 1). G is opposite 1 on the x-axis and opposite minus 3 on the y-axis. H is opposite minus 2 on the x-axis and opposite 3 on the y-axis.
