(1/4,-1/8);3y-5x< -5 determine whether the orded pair is a solution of inequality. Yes or NO?

put x = 1/4 and y = -1/8
3y - 5x = 3*(-1/8) - 5(1/4) = -13/8
but -13/8 > -5, therefore, not a solution

NO,Using the orded pair, substitute it on the inequality
x=1/4 and y=-1/8
therefore,
3y - 5x = 3*(-1/8) - 5(1/4) = -13/8
but however we wanted 3y-5x< -5
and -13/8 > -5
therefore the orded pair is not a solution of inequality!!
Hope this helps!!

3y - 5x = - 3/8 - 5/4 = - 3/8 - 10/8 = -13/8
-13/8 is NOT < - 5
Answer is NO

No.... Using the orderd pair, substitute it on the inequality...
3(-1/8)-5(1/4)=5
-3/8- 5/4<-5
-3/8- 10/8<-5
-13/8<-5
-1.625<-5
THe answer is NO....
