Question

Graph 3x +4y=12 please

Answer 1

To help us to graph the 3x + 4y = 12, we can isolate y

`\begin{gathered} 3x+4y=12 \\ \\ 4y=12-3x \\ \\ y=(12)/(4)-(3)/(4)x \\ \\ y=3-(3)/(4)x \end{gathered}`

Therefore it's a line with equation

`y=3-(3)/(4)x`

We have y = 3 when x = 0, and x = 4 when y = 0, therefore
