# How do you write 4x+9y = 36 in slope intercept form?

the answer is $y = - \frac{4}{9} x + 4$
remember the formula for slope intercept form is $y = m x + b$ with $m x$ being the slope and $b$ being the y-int so for this, you have to get $y$ by itself. first take care of $4 x$ b/c that will give you slope. so subtract $4 x$ from both sides. now you have $- 4 x + 36 = 9 y$ and now divide $9$ from both sides to leave only $y$ and now you divide $9$ from everything on both sides. it just leaves $y$ on one side but you have to do $\frac{4}{9}$ and $\frac{36}{9}$ on the other side. and you have your answer
