can someone please help me fix my math problem? please? I will fan and give a medal!!
Question~
write the following inequalities in y = mx + b form. Please show all work.
–3x –4y 12
My answer~
Add 3x to both sides,
-4y12+3x
Divide both sides by -4
(-4) -4y12+3x(-4)
(-4)/-4=1
3/(-4)= 0.75
=
1y12+0.75x

My answer~
 Add 3x to both sides,
    -4y>12+3x
     Divide both sides by -4
    (-4) -4y>12+3x(-4)

@mathstudent55 @tom982 @welshfella  could one of y'll try to help me? Please?

anonymous · Answer

When you divide by a negative, you have to change the sign in the inequality. For example:

-1 > -2
Divide by -1 to get 1 > 2 which is incorrect.

Instead, it should be -1 > -2 goes to 1 < 2.

In addition to Tom's comment, your final answer is not in y = mx + b form. You flipped the places of mx and b. :)

Also, you can simplify 1y to just y.

So here is the only place I messed up?
 (-4) -4y>12+3x(-4)

Right, you're dividing, not multiplying.
$$\frac{ -4y }{ -4 } > \frac{ 12 + 3x }{ -4 }$$
This leaves you with$$y < -\frac{ 3 }{ 4 }x -3$$
