SOLUTION
The equation of a line written in slope-intercept form is
![y=mx+b](https://img.qammunity.org/2023/formulas/mathematics/high-school/smsb8cbft03lwblmi49nf2l6jby2ofxzws.png)
Where
![\begin{gathered} m=\text{slope } \\ b=y-\text{intercept } \end{gathered}](https://img.qammunity.org/2023/formulas/mathematics/college/oqe50zcncr0qxw0akxlpnzyh7a2z6cs948.png)
The y-intercept is the point where the line cuts the y-axis.
From the graph given, the line cut the y-axis at y= -2
the y-intercept is
![(0,-2)](https://img.qammunity.org/2023/formulas/mathematics/high-school/mqjil0hmcamvt3t48grgo49bs7whom4ejf.png)
Hence, we have
![\begin{gathered} \text{ Since b is the y-intercept, } \\ b=-2 \end{gathered}](https://img.qammunity.org/2023/formulas/mathematics/college/nxce8ivlb12a68by8vfjgxbbiawt9fe2cg.png)
Therefore
Answer ; b = -2
The second option
