Yes. 6y = 18x can be cancelled down to y = 3x. If drawn on a graph, the gradient of the straight line at any given point would be 3. The line also crosses the point (0, 0) [the origin]

Is 5x plus 3 equals 8y plus 3 a direct variation?
Yes.
Find an equation of variation where y varies directly as x One pair of values is y equals 80 when x equals 40?
Find an equation of variation where y varies directly as x. One pair of values is y = 80 when x = 40
Find an equation of variation where y varies directly as x and y equals 8 when x equals 2 find y when x equals 10?
40
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.
Does the function y equals 8x represent a direct or inverse variation?
Direct
Does y equals 7x represent a direct variation?
y=7x
Is the equation 3x - 5 equals y an example of direct variation?
-2
Is y equals 3x direct variation?
Yes, it is direct variation.
Is y equals 2x plus 5 a direct variation if so what is the constant of variation?
No, it is not a direct variation.
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
Does y vary directly with x in the equation y equals 5x?
Yes, this is an example of direct variation.A:This is a direct variation because both are in the numerator of a fraction and on opposite sides of the = sign. If they are both on the same side of the equals sign, then one would have to be in the numerator and the other in the denominator for them to be a direct variation.
Find a equation of variation where y varies directly as x and y equals 0.8 when x equals 0.4?
direct variation: y = kx y = kx k = y/x = 0.8/0.4 = 2
Can ax plus by equals c be a direct variation if a and b and c does not equal 0?
No, direct variation is "y=ax." In direct variation a equals any real constant, b=1, and c must equal zero. If any of thee conditions are changed, it is not direct variation.
Is y equals 24 divided by x a direct variation?
No, this is an inverse variation.
What is the constant of variation in the direct variation x-y equals 0?
1
