The slope intercept form is
y = mx + c
4x + 9y = -36
We should rearrange to keep it in y = mx + c order
And therefore we do this:
take the x to the other side
9y = -4x - 36
Divide both sides by 9 to be y alone
\(\frac{9y}{9}\) = \(\frac{4x - 36}{9}\)
9 and 9 cancels out
y = \(-\frac{4x}{9}\) - 4
The first option is the answer
