What is the equation of direct variation if y is 16 when x is 20?
The equation can be written as y = 16x/20 which can be simplified to y = 4x/5
What is the general form of a direct-variation equation?
y = cx where x and y are the two variables and c is a constant.
When x is 2.25 y is 6.75 y varies directly with x write the direct variation equation in the form y kx. direct variation equation find y when x is 4.2. when x 4.2 y?
y = 3x because when x is 2.25 y is 6.75 a ratio of 1 to 3 and so when x is 4.2 y is 12.6
How do you find the equation for a direct variation?

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 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.
Is y 4x 1 a direct variation?
The equation ( y = 4x + 1 ) is not a direct variation. In a direct variation, the relationship can be expressed in the form ( y = kx ), where ( k ) is a constant and there is no constant term added or subtracted. Since this equation includes the constant term ( +1 ), it does not meet the criteria for direct variation.
How would you determine the equation of a direct variation?
To determine the equation of a direct variation, you start by identifying the relationship between the two variables, typically represented as ( y ) and ( x ). The equation can be expressed in the form ( y = kx ), where ( k ) is the constant of variation. To find ( k ), you can use a set of values for ( y ) and ( x ) and solve for ( k ) by rearranging the equation to ( k = \frac{y}{x} ). Once you have ( k ), you can write the complete equation of the direct variation.
How do you know if x and y are 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.
Which equation represents a direct linear variation?
Y=1/x
What the three ways to represent a 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
