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.
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?
straight line
What does a direct proportion look like on a graph?
A straight line, through the origin, sloping up from left to right. The gradient of the graph will be the constant of proportionality.
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.

Does a graph showing direct proportion always have to be a straight line?
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
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 the characteristics of a rate?
It represents a direct proportion and whose graph 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
When a graph of 1 quantity vs another results in a straight line the quantity are?
When quantities are related this way we say that they are in direct proportion.
If the relationship between the manipulated variable and the responding variable is a direct proportion what will a line graph of this relationship look like?
Straight line.
What relationship exist between two variables when their ratio is constant?
Direct proportionality. Their graph would be a straight line through the origin, with the slope equal to the ratio.
