Response:
Second option: 
Third option: 
Detailed explanation:
The missing graph has been provided.
The attached image illustrates the graphing of the following system of linear equations:

Notice the intersection of the lines.
According to the definition, if lines in a system of equations intersect, then there is only one solution. This implies that the intersection point is the solution to that system. This can be expressed as:

Represented by "x" for the x-coordinate and "y" for the y-coordinate.
Here, it's noticeable that:
- The x-coordinate of the intersection point lies between
and
.
- The y-coordinate of the intersection point is situated between
and
.
Therefore, you can conclude that the forthcoming points (Refer to the options given in the exercise) are potential approximations for this system:

Response:
We are provided with:

The interpretation of
signifies the extent of variation in the response variable accounted for by the explanatory variable within the model
Thus, the interpretation of
indicates that 12.7% of the variation in the GPA response variable is attributed to the job-related explanatory variable in the specified linear regression model.
