-6+9i
9i = 6
i = 6/9 or 2/3
we are given the equation 3y = -7x - 18 and is asked whether y is directly proportional to x and if it is, we find the constant of variation. In this case, we simplify the equation into y = -7/3 x -6. In this case, we can see that y is proportional to x with a constant of proportionality of -7/3
Distribute 6 into the numbers in parenthesis
