(1/4,-1/8);3y-5x< -6 determine whether the orded pair is a solution of inequality. Yes or NO?

3y - 5x < 6
assuming x = 1/4, y = -1/8, plug in and solve:
3*(-1/8) - 5*(1/4) < 6
-3/8 - 5/4 < 6
-3/8 - 10/8 < 6
-13/8 < 6
-1.625 < 6
The answer is YES
Re: Como's answer below, he writes "-13/8 > -6", this is TRUE, -13/8 IS greater than -6, so even if you write it that way the answer is still YES.

NO,utilising the orded pair, substitute it on the inequality x=a million/4 and y=-a million/8 consequently, 3y - 5x = 3*(-a million/8) - 5(a million/4) = -13/8 yet although we would have cherished 3y-5x< -5 and -13/8 > -5 consequently the orded pair isn't a answer of inequality!! desire this helps!!

substituting the ordered pairs:
3(-1/8)-5(1/4)<-6
-3/8-5/4<-6
-1.625<-6
meaning... the order pair is NOT a solution of the inequality..

3y - 5x < - 6
3(- 1/8) - 5(1/4) < - 6
- 3/8 - 5/4 < - 6
- 3/4 - 10/8 < - 6
- 13/8 < - 6
- 1 5/8 < - 6
- 1.625 < - 6
If you analyze negative integers - 1.625 is more positive than - 6
- 1.625 is not equal to - 6
since - 1.625 is more positive than - 6. you can state that - 1.625 is more than - 6

3y - 5x = -3/8 - 5/4 = -3/8 - 10/8 = -13/8 > - 6
NO is the answer!
