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.
What On a graph which type of line shows a direct proportion?
straight line
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.
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.
How can you determine if a graph forms a direct proportion?

What On a graph which type of line shows a direct proportion?

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.
How do you determine direct and inverse proportion on graphs?

Does a direct proportion have to have a slope of 1?
No, a direct proportion does not have to have a slope of 1. A direct proportion means that two quantities increase or decrease together at a constant ratio, which can be represented by the equation (y = kx), where (k) is a constant. The slope of the line in a graph of a direct proportion is equal to this constant (k); if (k) is greater than 1 or less than 1, the slope will reflect that but still indicate a direct relationship.
Does directly proportion pass through origion in graph?
Oh, dude, let me break it down for you. So, like, a direct proportion means as one variable increases, the other also increases at a constant rate. And guess what? If you start at the origin (0,0) on a graph, that's like ground zero, where all the action begins. So yeah, a direct proportion totally passes through the origin on a graph. Cool, right?
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.
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
