Answer:
53.13 degrees
Step-by-step explanation:
From the shape of the graph, we can see that the plotted line forms a right-angled triangle with the x and y coordinates. As a result, we can use laws that govern the geometry of right-angled triangles to evaluate the solution.
[tex]tan \theta = opposite/ adjacent[/tex]
The opposite side in this case is the side directly facing the angle Θ. This is the y - axis value = -4
The adjacent side in this case is the side above the angle Θ. This is the y - axis value = -3
[tex]tan \theta = (-4/-3)\\\theta = tan ^-1(4/3) = 53.13 degrees[/tex]
