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.
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 from an equation if the line will pass through the origin?
For any polynomial equation, there must be no constant term.For equations in general there is no easy way. Substitute 0 for each of the variables and if the resulting expression is 0 then the line passes through the origin.
A circle centered at the origin runs through the point 5 12 What is the radius of the circle?
13 good luck
What is the equation of the line whose graph passes through the origin and has a slope of 1?
Slope = 1Y-intercept = 0Y = X
What do all direct variation graphs have in common?
All direct variation graphs are linear and they all go through the origin.
The graph of a linear relationship will always pass through the origin?
Not always
Does simple linear regression always go through the origin?
No.
What is a linear function that goes through the origin?
it is just that- a linear function that goes through ther origin. ======================================================= Any equation y = ax, where a is a constant, will do so.
How would you answer the following linear equation and what would be the solution set y equals 32.25x and y equals 26.30x?
The graphs of those two equations are straight lines, each of which passes through the origin. The origin is the common solution ... the point (0, 0).
What are the properties of proportional and non-proportional tables and graphs?
If two quantities are proportional, then they have a constant ratio.If the ratio is not constant, the two quantities are said to be non-proportional.Proportional will always go through the origin on a graph. (0,0)Graph will always be a straight line.Non-proportional line does not go through the origin.
What is the definition of proportional relationships in graphs?
Either a straight line through the origin or a hyperbola.
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.
How do you evaluate graphs of proportional relationships?
They are straight lines through the origin and their gradient is the constant of proportionality.
What is an example of an linear parent function?
the line that crosses through the origin
What shape does the grapg of a linear relationship take?
A straight line that goes through the origin.
What if y equals kx?
You then have a linear relationship, or a direct variation. A straight line through the origin.
