Assuming both the scales on the graph are linear (that is to say that the numbers go up evenly) then YES, a graph which shows direct proportion must be a straight line. It must also pass through the origin (0,0). A straight line which does not pass through the origin is NOT showing direct proportion. Duncan

What is the relationship between two circles?
Their circumferences are in direct proportion to their radii. Their areas are in direct proportion to the square of their radii.
Does the graph of an inverse variation pass through the origin?
Inverse variation does not pass through the origin, however direct variation always passes through the origin.

How can you determine if a graph forms a direct proportion?
If it is a straight line through the origin then it represents a direct proportion.
On a graph which type of line shows direct proportion?
This graph states, therefore, that A is directly proportional to B. It also states that ... thus showing that this straight line through the origin represents a direct proportion. ... what you are talking about, because there are other types of proportions.
What is a graph of a direct proportion?
A kind of weird line that is straight.
What On a graph which type of line shows a direct proportion?

What is the definition of direct SQUARE proportion?
In a nonlinear graph showing the relationship between two variables where one is related o the second power of he other. This will no be in a straight line, but will curve upward and it is known as direct square proportion.
Why the straight line in the graph doesn't start from zero?
Unless it is a direct proportion, the straight line does not have to start from zero.
What is the characteristics of a rate?

What is the graphical representation of direct proportion?
A straight line through the origin, with a finite non-zero slope.
What do you know about direct proportion and inverse proportion?
direct proportion: y=kx inverse proportion: y=k/x
What type of line shows a direct proportion on a graph?
A direct proportion on a graph is represented by a straight line that passes through the origin (0,0). This line has a constant slope, indicating that as one variable increases, the other variable increases at a consistent rate. The formula for a direct proportion can be expressed as ( y = kx ), where ( k ) is the constant of proportionality.
How do you determine direct and inverse proportion on graphs?
If the variables x and y are in direct proportion then the graph of y against x is a straight line through the origin. If the variables x and y are in inverse proportion then the graph of y against x is a rectangular hyperbola. Alternatively, the graph of y against 1/x (or 1/y against x) is a straight line through the origin.
If the relationship between the manipulated variable and the responding variable is a direct proportion. What will a line graph of this look like?
straight line
