What is the variable k in a direct variation?
the 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 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.
Does direct proportion need to have a slope of 1?
No, direct proportion does not necessarily need to have a slope of 1. A direct proportionality relationship means that as one variable increases, the other variable increases at a constant rate, which can be represented by the equation (y = kx), where (k) is a constant. If (k = 1), the slope will be 1, but any positive value of (k) will still represent a direct proportion, just with a steeper or shallower slope.
Is -3x -35y equals 14 a direct variation?
no. direct variation implies that you can simplify the problem into several forma which are equivalent to y/x = k in which k is called the constant of variation. one of these equivalent forms would by y = kx + 0 (slope intercept form) in which the y intercept must be 0 rearranging your equation gives a y- intecept of -14/35 which reduces to -2/5 since this is not zero. this is not direct variation.

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.
Does direct proportion need to have a slope of 1?

A direct proportionality relationship means that as one variable increases, the other variable increases at a constant rate, which can be represented by the equation (y = kx), where (k) is a constant.

What does the k represent in the direct variation ykx?
The constant of variation in a direct variation is the constant (unchanged) ratio of two variable quantities. The formula for direct variation is. y=kx (or y=kx ) where k is the constant of variation .

What does k represent in direct variation?
The constant.
What is the definitions of direct variation?
x/y=k
What is the difference between direct variation and inverse variation?
Direct variation is the ratio of two variable is constant. Inverse variation is when the product of two variable is constant. For example, direct variation is y = kx and indirect variation would be y = k/x .
Does a direct proportion have to have a slope of 1?
No, a direct proportion does not have to have a slope of 1. A direct proportion means that two quantities increase or decrease together at a constant ratio, which can be represented by the equation (y = kx), where (k) is a constant. The slope of the line in a graph of a direct proportion is equal to this constant (k); if (k) is greater than 1 or less than 1, the slope will reflect that but still indicate a direct relationship.
What is the difference direct variation and inverse variation?
Direct variation is the ratio of two variable is constant. Inverse variation is when the product of two variable is constant. For example, direct variation is y = kx and indirect variation would be y = k/x .
