1) Examining the graph, we can see the labeled point (3,-6)
2) Therefore we can plug it into that formula below this point and find the point-slope form of this linear function. But at first, we need to find the slope m, picking another point (0,-4)
[tex]m=\frac{y_2-y_1}{x_2-x_1}\Rightarrow m=\frac{-4-(-6)}{0-3}=\frac{2}{-3}=-\frac{2}{3}[/tex]
2.2) Now we can plug it into that the slope and one point
[tex]undefined[/tex]
