## shenita05 4 years ago Determine whether each equation has the given ordered pair as a solution. 5x − 3y = 15; (0, 5)

1. xokatexo

Let x=0 5x − 3y = 15 5(0) − 3y = 15 0-3y=15 3y=15 -- --- 3 3 y=5 (0,5)

2. shenita05

thank you cause i wasnt sure of the question

3. amistre64

?? you got an error there

4. xokatexo

can you give me a medal?

5. amistre64

for starters; when x = 0 there is nothing over there and your left with -3y = 15 -3(5) does not equal 15

6. shenita05

amistre where would be the error ok hold on xok

7. xokatexo

-15

8. xokatexo

whoops

9. amistre64

xok dropped the - sign from the y

10. amistre64

but its good to know how to dbl chk to spot for those ..... the steps were good, just missed it by thaaaaaatt much lol

11. shenita05

so -3/15 y=-5?

12. xokatexo

yeah

13. shenita05

okay thax for checking amistre

14. amistre64

just plug in your point values and see if it matches really (x=0, y=5); 5(0)-3(5)=15 0 -15 = 15 -15 = 15 is a contradiction; so the point aint part of the equation

15. xokatexo

can we have medals?

16. amistre64

since ya tried :)

17. xokatexo

grrr :)

18. shenita05

so amistre im safe with ur steps?

19. xokatexo

:(

20. amistre64

yep; if the point fits and makes it true; its good .... otherwise toss it

21. shenita05

thanx both no sad faces u guys are helping me ! i appreciate it ok

22. amistre64

:) youre welcome

23. shenita05

It's not a solution. The answer would come out as -15 instead of 15

24. xokatexo

the solution is if there are 2 lines... the solution would be where the two lines meet
