![-(3)/(4)](https://img.qammunity.org/2020/formulas/mathematics/high-school/lkahup86mpuszjd5vk16zuxkjntjw8msjm.png)
Y-intercept: 399
Slope-intercept form:
![y=-(3)/(4)x+399](https://img.qammunity.org/2020/formulas/mathematics/college/munwb0gxbb7zxgi8fuxq56zrskp8s03sm3.png)
Explanation:
1. The equation in Standard form is given in the problem:
![3y+4y=1596](https://img.qammunity.org/2020/formulas/mathematics/college/4hr45fgas9rxylob9vmyyl1t89c9o31y48.png)
2. Then, to write the equation of the line in slope-intercept form
, where m is the slope and b is the y-intercept, you must solve for y as you can see below:
![4y=-3x+1596\\y=(-3x+1596)/(4)\\y=-(3)/(4)x+399](https://img.qammunity.org/2020/formulas/mathematics/college/bk4pgsa08jnlsctzh1g0pqw88opr3qtxxb.png)
3. Therefore, the slope and the y-intercept are:
![m=-(3)/(4)\\b=399](https://img.qammunity.org/2020/formulas/mathematics/college/26lded6qgkprx8zuho2zdu3uzoswvuwb25.png)
