Example: 2/3 y = x this simple example means this: you are to find the fraction that multiplies to it and equal one. (of course, just flip it around) then move THAT behind x. It vary directly if it is the same as this - y=kx Tip: subtraction and addition automatically says "no , this does not vary directly

Does x vary directly to y?
The answer depends on x and y. They are not defined for this question.
Y equals 12x do x and y vary directly?
X and Y are directly propotinal.If one is varing other is varing too.
Does y vary directly as x in y equals 8x?
Yes. Directly and 8 times as fast.
The variables x and y vary directly when x equals -5 and y equals 21 what is the constant of variation?
y = kx k = y/x = 21/-5 = - 21/5
If y varies directly x squared find k when y -9 and x-1?
-8
Does x vary directly to y?

Does y vary directly as x in this function y equals x plus 2?
No.
Y equals 12x do x and y vary directly?
X and Y are directly propotinal.If one is varing other is varing too.
Does y vary directly as x in y equals 8x?
Yes. Directly and 8 times as fast.
What does it mean for x and y to vary directly?
That means that if "x" varies by a certain factor, "y" will vary by the same factor. For example, if "x" is double, then "y" will also double.
The variables x and y vary directly when x equals -5 and y equals 21 what is the constant of variation?
y = kx k = y/x = 21/-5 = - 21/5
If y varies directly as x and y 18 when x 24 find x when y 15?
If y varies directly as x and y is 18 when x is 24, then y is always three fourths of x. So if y is 15, then x is 20.
If y varies directly as x and y 36 x 9 then what is the value of x when y 12?
If y varies directly as x and y is 36 when x is 9, then y is always four times the value of x. So if y is 12, then x is 3.
If y varies directly as x squared find k when x 2 and y 8?
If y varies directly as x and if x = 2 when y = 8 then k = 4.
If y varies directly as x and y equals fifteend and when x equals three find y when x equals twelve?
y is directly proportional to x. When y = 15, x = 3 therefore y = 5x When x = 12, then y = 5 x 12 = 60.
What is the constant of variation k if x .5 and y 1 Assume y varies directly as x?
If y varies directly as x then k = 2.
What is the difference between directly propotional and inversely proportional?
In directly proportional the two variable vary in the same "direction". So, if one increases, the other increases.In inversely proportional, the two variable vary in opposite "directions". So, if one increases, the other decreases.
