Yes.
If the graph is a straight line through the origin, sloping upwards to the right, then it is a proportional linear relationship.
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.
The axes of coordinate planes intersect at the point of origin.
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..
The graph of a relationship in which two variables are in direct proportion is a straight line through the origin, whose slope = the rate of change = the constant of proportionality.
It is true in the case of inversely proportional relationship.
If the graph is a straight line through the origin, sloping upwards to the right, then it is a proportional linear relationship.
If it passes through the origin
It can be either a straight line through the origin or a hyperbola.
It is a graph of a proportional relationship if it is either: a straight lie through the origin, ora rectangular hyperbola.
If two quantities are proportional, then they have a constant ratio.If the ratio is not constant, the two quantities are said to be non-proportional.Proportional will always go through the origin on a graph. (0,0)Graph will always be a straight line.Non-proportional line does not go through the origin.
The graph of a proportional relationship has the same unit rate, is a straight line, and starts at the origin.
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.
A straight line through the origin, and with a positive gradient (sloping from bottom left to top right).
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.
Not always
It's a slanted straight line that goes through the origin of the coordinates.
