We have the following:
We can confirm the intercepts with the y-axis, since it is when x = 0, in the case of the first equation it is 2 and in the second equation it is 1
Therefore, we limit ourselves to the answers C and D, now we can calculate the slope as follows:

The point are (0, 2) and (-6, -1)

The slope is 1/2, therefore, the equations are

The answer is the option C
