The equation y 8x is an example of inverse variation is this true?
No. This is not true. It is false. The equation is an example of direct variation.
What is the y-intercept of the graph of a direct variation equation?
Graphs of direct variation pass through the origin so the y-intercept would be 0.
Is it always sometimes or never true that an equation in slope intercept form represents a direct variation?
An equation in slope-intercept form (y = mx + b) represents a direct variation only when the y-intercept (b) is zero, making it (y = mx). If (b) is non-zero, the equation does not represent a direct variation, which is defined as a linear relationship that passes through the origin. Therefore, it is "sometimes" true that an equation in slope-intercept form represents a direct variation, depending on the value of (b).
Is the problem y equals 3x a direct variation if so what is the constant of variation?
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
How do you find the constant and slope for direct variation equations?
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.
How do you find the equation for a direct variation?
find the direct variation equation 3x+y=0
Which of these equations is a direct variation y equals -8x plus 1?
There is only one equation that is given in the question and that equation is not a direct variation.
The equation y 8x is an example of inverse variation is this true?
No. This is not true. It is false. The equation is an example of direct variation.
How do you know if an equation is direct variation?
There are three ways: a table, a graph, and an equation.
How do you know if the equation is a direct variation?
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
Which equation represents a direct linear variation?
Y=1/x
What the three ways to represent a direct variation?
equation, table or a graph
What is the y-intercept of the graph of a direct variation equation?
Graphs of direct variation pass through the origin so the y-intercept would be 0.

Does the equation 2y5x 1 represent a direct variation?
Without an equality sign the information given does not represent an equation.
Does y equal 1X show direct variation?
Yes. y = 1x is the same as y = x which is the simplest case of direct variation. If you consider the equation y = mx + b, then a direct variation will always have b = 0 (i.e. the graph goes through the origin). The value of m is called the "constant of variation", and the equation is usually written as y = kx.
