Question

Graph 3x +4y=12 please

Answer 1

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

$\begin{gathered} 3x+4y=12 \\ \\ 4y=12-3x \\ \\ y=\frac{12}{4}-\frac{3}{4}x \\ \\ y=3-\frac{3}{4}x \end{gathered}$

Therefore it's a line with equation

$y=3-\frac{3}{4}x$

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