I am stumped on the slope intercept form. 3x-4y = 12. I don't understand why the answer is 3/4x - 3. How does it become x?

    you should keep the x slope intercept form is y=mx+b where m is slope and b is y-intercept

    you need to solve for y\[\huge\rm 3x-4y=12\] move the `3x`to the right side and then -4

    ho would you cancel out the 3x from the left side ?

    3x - 4y = 12 3x - 3x -4y = -3x +12 -4y and then I don't know what do next.

    now how would you cancel out the -4 from the left side ?

    nice but don't forget it's negative so -4 :=)

    Yes I saw that but I had already hit post. So I've cancelled out 4 but I still don't understand how the answer becomes 3/4x -3. Where did the 12 go?

    \[\huge\rm y=\frac{ 3 x}{ 4 }+\frac{ 12 }{ -4 }\] 12/-4 = ? you can divide it right!
