Completing table of values

[brainfreze27]

I am new to this site and this is m first forum post. I am in desperate need of help with this math problem. I have no idea what to do when there is a number on the left side of the equal sign with the y. Can someone please explain this to me it would be greatly appreciated.
Thank You!

B

Thank you but could you explain how to do it because I have more problems like this and like i said i dont know what to do when there is a number with the y

Choice B is not the correct answer.

Jayshal is wrong.

ohh okay could you please explain the problem to me please it would be greatly appreciated

Substitute in x = -10 and solve for y.

What choices can you eliminate from that?

 

[Jayshal]

Sorry it's A
substitute a or b in the formula and to get final result you can move numbers to other side and change sign + to -
y-3=1/2(x+2)
y-3=1/2(-10+2)
y-3=-4
y-3(+3)=-4+3
y=1

do the rest of them like that

so it says y-3=1\2(x+2) when u say substitute and solve for y do you mean this
y-3=1\2(-10+2)
+3 +3
Y=1/2(-7+2)
Like this?

ohh i see what you did there

 

[lookagain]

y-3(+3)=-4+3 \(\displaystyle \ \ \ \ \ \)No parentheses! This would be the equivalent of the left-hand side equal to y - 3(3) = y - 9.

Okay so I used the method you said on this new problem and I have narrowed it down to B or D but how do i figure the x value if I only know Y

y + 2 = -4(x - 1)


Substitute 2 in for y and solve for x.

Do you know how to do that?

 

[brainfreze27]

y + 2 = -4(x - 1)


Substitute 2 in for y and solve for x.

Do you know how to do that?

No I dont could you show me please

I will show you, but then I will leave this thread, and I won't make a promise to come back due to other obligations.

y + 2 = -4(x - 1)

Substitute in y = 2:

2 + 2 = -4(x - 1)

4 = -4(x - 1)

4 = -4x + 4

4 - 4 = -4x + 4 - 4

0 = -4x

0/(-4) = -4x/(-4)

0 = x

or

x = 0

y + 2 = -4(x - 1)

Substitute in y = 2:

2 + 2 = -4(x - 1)

4 = -4(x - 1)

4 = -4x + 4

4 - 4 = -4x + 4 - 4

0 = -4x

0/(-4) = -4x/(-4)

0 = x

or

x = 0

4 - 4 = -4x + 4 - 4 what did you do here? i dont understand past where you distributed.

Hi brainfreze:

Is this homework? That is, are you taking a beginning algebra class, or is this self-study?

y + 2 = -4(x - 1)

Substitute in y = 2:

2 + 2 = -4(x - 1)

4 = -4(x - 1)

Alternatively, at this point divide both sides by -4:
-1= x- 1 and then add 1 to both sides.

4 = -4x + 4

4 - 4 = -4x + 4 - 4

0 = -4x

0/(-4) = -4x/(-4)

0 = x

or

x = 0

Okay thank you all i finished the assignment and i got an A!!! Thank you all!

 

[Quaid]
