To find the equation of a line in slope-intercept form you need to identify the slope (m) and the y-intercept (b)
To find the slope you use two point in the line:
Use the next formula to find the slope:
![m=(y_2-y_1)/(x_2-x_1)](https://img.qammunity.org/2023/formulas/mathematics/high-school/78uaqhwt0aws3qfwxigaftpihnmb1gzxtp.png)
![m=(-2-3)/(0-(-3))=(-5)/(0+3)=-(5)/(3)](https://img.qammunity.org/2023/formulas/mathematics/college/6psk4ls2nkvxry6dvmyifvge3iltad17xj.png)
The slope of the given line is m= -5/3
The y-intercept is the value of y when x is 0 (the point where the line cross the y-axis)
In this case the value of y when x is 0 is -2.
Then, you get the next equation for the given graph:
![y=-(5)/(3)x-2](https://img.qammunity.org/2023/formulas/mathematics/college/mujx0nr7xzbqdyzqhto6hss2vz65pue4z7.png)
