We obtain the figure by either plotting or finding the distances between the points:
Since all the distances of the four sides are equal, we have to check if the shape is either a rhombus or a square by the measuring the length of the diagonals
The diagonals are also equal; therefore, the figure is a square
If the relationship between two quantities is a proportional relationship, this relationship can be represented by the graph of a straight line through the origin with a slope equal to the unit rate.
