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
Their circumferences are in direct proportion to their radii. Their areas are in direct proportion to the square of their radii.
Inverse variation does not pass through the origin, however direct variation always passes through the origin.
No Direct Antonym
it is a math question bang bang
I need a real life example
If it is a straight line through the origin then it represents a 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.
A kind of weird line that is straight.
straight line
Unless it is a direct proportion, the straight line does not have to start from zero.
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.
It represents a direct proportion and whose graph is a straight line through the origin.
A straight line through the origin, with a finite non-zero slope.
direct proportion: y=kx inverse proportion: y=k/x
when both increaes its direct proportion and when one increase and othe decreases its inverse proportion.
Yes it does rely on direct proportion.
