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 do all direct variation graphs have in common?
All direct variation graphs are linear and they all go through the origin.
What is the direct of relationship in statistics?
graphs,distinguisment
What are the graphs of the inverse trigonometry functions?
If you reflect a function across the line y=x, you will have a graph of the inverse. For trigonometric problems: y = sin(x) has the inverse x=sin(y) or y = sin-1(x)
Why do scientists plot graphs?
It makes it easier to see trends and direct relationships in data.
What is the y-intercept of the graph of a direct variation equation?
Graphs of direct variation pass through the origin so the y-intercept would be 0.
Determine the inequality of the graphs?

Difference between the graphs of linear equations and a direct variation?
Linear has a slope direct does not but both go through the orgin
What are benefits of using graphs of frequency distribution?
to make patterns easier to determine

How are the graphs of inverse functions symmetric?
symmetric about the y-axis symmetric about the x-axis symmetric about the line y=x symmetric about the line y+x=0
What type of test are used to compare to data from an experiment to determine if results are due to chance?
line graphs
