A polynomial of degree zero is a constant term

The grouping method of factoring can still be used when only some of the terms share a common factor A True B False

The sum or difference of p and q is the of the x-term in the trinomial

A number a power of a variable or a product of the two is a monomial while a polynomial is the of monomials

I have recently been doing all these direct variation problems but not every linear relationship is a direct variation... But every direct variation is a linear relation!


Is every linear relationship a direct variation?

no.


What makes a decreasing linear relationship a direct variation?

if the line runs through the origin it is a direct variation no matter if it is increasing or decreasing


What if y equals kx?

You then have a linear relationship, or a direct variation. A straight line through the origin.

Is a linear function a direct variation?

yes * * * * * No, it is not. In a direct variation, if one of the variables is 0, the other MUST also be 0. In a linear function, they will be the intercepts.


How do you know that a direct variation is linear?

If the functional relationship is of the form y = cx where c is the constant of variation. In graphical form, it is a straight line through the origin.


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.


What do all direct variation graphs have in common?

All direct variation graphs are linear and they all go through the origin.
