What On a graph which type of line shows a direct proportion?
straight line
Which type of line shows a direct proportion?
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
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 is a graph of a direct proportion?
A kind of weird line that is straight.
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?
It represents a direct proportion and whose graph is a straight line through the origin.
What type of graph best shows the proportion of different population in a given area - a bar graph a pie chart or a line graph?
pie chart
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
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.
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.
