Step-by-step explanation:
xy=k
Value of k ; when ; x = - 3 and y = - 2
Put x = - 3 and y = - 2 into the equation :
(-3)(-2) = k
-3 * - 2 = k
6 = k
The constant of variation k = 6

Step-by-step explanation:
Let
y ----> Susannah's account balance
x ---> is the amount of time in months
we have

This is a linear equation in slope intercept form
where
The slope or unit rate is equal to

The y-intercept or initial value is equal to

Remember that
One year is equal to 12 months
so
For x=12 months
substitute in the linear equation
