There are three ways: a table, a graph, and an equation.
Y=1/x
equation, table or a graph
The equation can be written as y = 16x/20 which can be simplified to y = 4x/5
y = cx where x and y are the two variables and c is a constant.
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 .
find the direct variation equation 3x+y=0
When two variables are related in such a way that the ratio of their values always remains the same, the two variables are said to be in direct variation. y=2x is direct variation y=x+2 is not direct variation
There is only one equation that is given in the question and that equation is not a direct variation.
No. This is not true. It is false. The equation is an example of direct variation.
Without the rest of the equation it is not possible to tell. * * * * * If the equation is in the form y = k*x where k is a non-zero constant, then it is.
Y=1/x
equation, table or a graph
Graphs of direct variation pass through the origin so the y-intercept would be 0.
y=3x is a direct variation in that y varies directly with x by a factor of 3. Any linear equation (a polynomial of degree 1, which is a polynomial equation with a highest exponent of 1), is a direct variation of y to x by some constant, and this constant is simply the coefficient of the "x" term. Other examples: y=(1/2)x is a direct variation, and the constant of variation is 1/2 y=-9x is a direct variation, and the constant of variation is -9
For a direct variation equation the constant MUST be 0. Then the ratio of a pair of values of the two variables is the slope.
Without an equality sign the information given does not represent an equation.
Without an equality sign the given expression can't be considered to be an equation.
