Given
- 3y = - 
Multiply both sides by 5 to eliminate the fraction
- 15y = - 6 ( divide both sides by - 15 )
y =
=
=

^if you simplify, that would be your answer.
Step-by-step explanation:
the rate of change is officially
(f(x2) - f(x1)) / (x2 - x1)
but for a line function (as we have here) this is totally easy : it is the slope of the line.
and that means it is the factor of x.
in our case this is -3/2.
because the slope of a line is the ratio "y coordinate change / x coordinate change". and that is exactly corresponding to the general rate of change definition above.
