Is y9x 1 a direct variation function?
No.
Does the function y equals 8x represent a direct or inverse variation?
Direct
Is the direct variation of two variables always a linear function?
YES...A direct variation is a linear relationship in which y-intercept is always 0.
Is the constant of variation the same as slope?
yes y=kx is the formula for direct variation, and k represents constant of variation which can also be called slope.
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.
Is y9x 1 a direct variation function?
No.
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.
What is direct square variation in math?
direct square variation is a function that relates the same or equal constant ratio. It is a function that is typically used in different kinds of algebra.
Which equation represents a direct linear variation?
Y=1/x
Does the function y equals 8x represent a direct or inverse variation?
Direct
When is a linear function considered to be a direct variation?
Direct variation means that a linear function can be written as y = kx. The y-intercept must be (0, 0). The constant, k, is the slope.
Is the direct variation of two variables always a linear function?
YES...A direct variation is a linear relationship in which y-intercept is always 0.
Is the constant of variation the same as slope?
yes y=kx is the formula for direct variation, and k represents constant of variation which can also be called slope.
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.
What is the compares in constant and variable rate of change?
Tell whether the equation -4x+ 2y = -2 represents a direct variation. If so, identify the constant of variation.
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
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.
