The value of x varies directly with y, and when x= 1/3,y = 12. Write an equation to represent the direct variation. Enter the equation with no spaces. If "k" is a fraction, reduce the fraction to simplest form and enter it without spaces.
Equation:

Equation:

Step-by-step explanation:

The equation that represents a direct variation between variable x and variable y is given as . Where, k is the constant of proportionality.

Find the value of k given that x = ⅓ and y = 12.

Plug the values into the equation.

Multiply both sides by 3

Substitute the value of k into

Equation:

the answer is (4,3)

since the rule for r0, 90º is (-y,x) and it was already applied to form the image, all you have to do is reverse the answer using this formula.

the 8 in 8,420 is in the thousands place so it's value is 8 thousand.

the 8 in 6,870 is in the hundreds place so it's value is 8 hundred.

divide 8000 by 800 to find the answer:

8000 / 800 = 10

the 8 in 8,420 is 10 times greater than the 8 in 6,870
