In order to determine if this ordered pair is a solution, substitute the appropriate values in for x and y into the equation and see if both sides equal. If the do, it's a solution. If not, it's not.
In this case x=-3 and y=-5
The y=3x-4 becomes
Both sides are not equal, therefore (-3,-5) is not a solution of the given equation.
