Given:
x = 4
y = 36
Find the equation that relates to x and y.
Solution:
In order to find the equation that relates to x, and y, we simply need to find the constant of variation, which can be solve by simply multiplying x and y.
k= xy
k = (4)(36)
k =144
144 = xy
In order to solve for x, we substitute the value of y, hence in order to solve for y, we substitute the value of x in the formula for the constant of variation.
Final answer:
144 = xy
