Mikayla_Rose Group Title Can you help me with these math questions? Did I get them right? Is (0,3) a solution to the equation y=x + 3? I answered yes. Is (1, -4) a solution to the equation y= -2x? I answered no. Thanks one year ago one year ago

1. goformit100

yes its correct :) Keep it up.

2. jim_thompson5910

let's check (0,3) means x = 0 and y = 3 y=x + 3 y=0 + 3 ... replace x with 0 (since x = 0) 3 = 0 + 3 ... replace y with 3 (since y = 3) 3 = 3 since that's true, this means that (0,3) is a solution to y = x+3

3. jim_thompson5910

so you are correct on the first one

4. Mikayla_Rose

Thanks, do you think you could help , me with some more?

5. goformit100

Sure Madam, I promise to help you.

6. jim_thompson5910

checking the second one y= -2x -4 = -2(1) ... plug in (1,-4) -4 = -2 that is false, so (1,-4) is not a solution to y = -2x again you are correct

7. goformit100

Second is too correct.... answer is false

8. Mikayla_Rose

Yay :) I am writing the other one thanks both of you

9. Mikayla_Rose

Look at the following points. (4,0), (3, -1), (6,3). (2, -4) What are the solutions to y=x - 4? Choose all correct answers.

10. Mikayla_Rose

I am confused on this one

11. goformit100

Put the coordinates and check the Equality

12. goformit100

Try with each of them

13. Mikayla_Rose

How?

14. goformit100

Simply put the coordinates Like y=x - 4 we know (4,0) put the value 0 = 4 - 4 0 = 0 hence (4,0) is a solution of the given equation.

15. goformit100

Did you got the Idea ?

16. Mikayla_Rose

Ohhh I get it hold up

17. goformit100

Now show me your working with (3, -1)

18. Mikayla_Rose

Okay is it 1?

19. goformit100

put the values on both side and then check it

20. Mikayla_Rose

1- = 3 - 3?

21. Mikayla_Rose

Like that?

22. goformit100

yes

23. goformit100

y=x - 4 check it for (3, -1) = (x,y) -1 = 3 - 4 -1 = -1 Hence (3, -1) is the solution of the given Equation

24. Mikayla_Rose

So that one is right as well?

25. goformit100

ya

26. goformit100

Put (6,3) and now try.

27. Mikayla_Rose

6= 3-3

28. goformit100

no not like that put the value of 'x' and 'y' which you are checking for in the Equation y=x - 4

29. Mikayla_Rose

okay hold up

30. Mikayla_Rose

d and a are wrong

31. goformit100

No, c and d are wrong.

32. Mikayla_Rose

oh.. /.\

33. goformit100

/.\ means ?

34. Mikayla_Rose
