A coordinate system is a method of determining the position of points or other geometric components on a manifold. The points which vary are on a graph where y varies directly with x are (-1, 1), (0, 0), and (-5, 5).
<h3>What are coordinates?</h3>
A coordinate system is a method of determining the position of points or other geometric components on a manifold, such as Euclidean space, by using one or more integers, or coordinates.
Given that y varies directly with x, therefore, we can write,
y∝x
y = kx
Also, y=3 and x=-3, therefore, the value of k can be written as,
3=k(-3)
k=-1
Now, the points which vary are on a graph where y varies directly with x are (-1, 1), (0, 0), and (-5, 5).
