Question 52690
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
-5=3(-3)-4
-5=-9-4
-5=-13
Both sides are not equal, therefore (-3,-5) is not a solution of the given equation.
