What else can I help you with?
What does the graph of an inverse variation look like?
A hyperbola.
Does the graph of a direct variation pass through the origin?
yes, a graph of a direct variation must pass through the origin because direct variation is always in form of y=mx where x and y are variables and m is a constant.
How can you tell by examining a graph if a line represents a direct variation?
The graph must be linear and pass thru the origin
Why does the graph of an equation expressing direct variation always pass through the origin?
For a direct variation, y=kx where k is the constant of variation if x =0 then y=0 and the graph of y=kx passes through the origin. -Indiana Prentice Hall Algebra 2 Text Book.
How does the constant of variation affects the appearance of the graph of a direct variation function?
The formula direct variation is xk=y, where k is the constant of variation.Direct variation functions always pass through the origin. Direct variation functions are linear functions (goes in a straight line), except that they pass through the origin. Regular linear functions don't pass through the origin. That is the only difference.
Is this a joint variation or combined variation a 7bc?
Joint variation
What is a joint bar graph?
A joint bar graph is a joint set of graphs.
Can slope k of a direct variation be positive?
The slope of the graph of a direct variation is always positive.
What does the graph of an inverse variation look like?
A hyperbola.
Find the constant of variation and the slope of the given line from the graph of y equals 2.5x?
find the constant of variation and the slope of the given line from the graph of y=2.5x
How do you use joint variation in a sentence?
i have no clue
What does k correspond to in a direct variation function?
k is the constant of variation and is the gradient (slope) of the relevant graph.
Does the graph of a direct variation pass through the origin?
yes, a graph of a direct variation must pass through the origin because direct variation is always in form of y=mx where x and y are variables and m is a constant.
Do the slope of direct variation changes as you move along the graph?
No.
How can you tell by examining a graph if a line represents a direct variation?
The graph must be linear and pass thru the origin
Does the graph of an inverse variation pass through the origin?
Inverse variation does not pass through the origin, however direct variation always passes through the origin.
What is general shape of a graph of an inverse variation relationship?
Cartestian plane
