If y varies directly with x and y doubles then x?

The second one doesn't represent a function, because for some values of "x", you get two different values for "y" (which should not happen, if that were a function).
In every function, you must have a single "y" value for each "x" in the domain.

In order to see it better, you can trace a vertical line onto that graph.
If that line and the graph intersects in more than one point, then that graph doesn't represent a funcion.
Look into the attached picture and see. That vertical red line and the graph intersects in two distinct points. Therefore, it can't represent a function.
Any doubt? Please, comment below.

For this question, we can use the same side interior angle theorem.
Angles 1 and 2 are same side interior angles, which means that they are the interior angles on the same side.
To find the angle measure of the angles, we can plug in the value we have.
To find if the oars are parallel, we can use the same side interior angle theorem, which states that if the same side interior angles are supplementary, the lines are parallel.
Seeing as the angles are supplementary, the oars are parallel to each other.
Hope this helps.
頑張って!
