All will apply except for (A, C, and E) because those lengths are less than 4/6. So (B, D and F) are the correct answers.
Alternate interior angles are equal, thus the given alternate interior angle is 80 degrees.
Therefore, x = 80 - 15 = 65 degrees.
For this case we have that by definition, the equation of the line in the slope-intersection form is given by:
Where:
m: It's the slope
b: It is the cut-off point with the y axis
By definition, if two lines are parallel then their slopes are equal.
We have the following line:

Thus, the slope is:
Then 
So, the line is of the form:

We substitute the point
and find b:

Thus, the equation is:

Answer:
