It is true in the case of inversely proportional relationship.
It is a graph of a proportional relationship if it is either: a straight lie through the origin, ora rectangular hyperbola.
The graph of a proportional relationship has the same unit rate, is a straight line, and starts at the origin.
It can be either a straight line through the origin or a hyperbola.
It's a slanted straight line that goes through the origin of the coordinates.
A straight line through the origin, and with a positive gradient (sloping from bottom left to top right).
If the graph is a straight line through the origin, sloping upwards to the right, then it is a proportional linear relationship.
Yes.
It is a graph of a proportional relationship if it is either: a straight lie through the origin, ora rectangular hyperbola.
The graph of a proportional relationship has the same unit rate, is a straight line, and starts at the origin.
It can be either a straight line through the origin or a hyperbola.
It is a relationship of direct proportion if and only if the graph is a straight line which passes through the origin. It is an inverse proportional relationship if the graph is a rectangular hyperbola. A typical example of an inverse proportions is the relationship between speed and the time taken for a journey.
It's a slanted straight line that goes through the origin of the coordinates.
If the scales on the two axes are linear, then the graph must be a straight line through the origin which is not one of the axes..
A straight line through the origin, and with a positive gradient (sloping from bottom left to top right).
The graph of a linear proportion will be a straight line passing through the origin. The equation will have the form y = mx, also written as y = kx.
It must be a straight line. It must pass through the origin.
It is a straight line through the origin.
