Roger warns $13 for each hour of dog walking. how many hours in all will it take roger to earn a total of $26

  x=-2

Step-by-step explanation:

Since the original equation is x=4 which means that it is a straight line. For 2 lines to be parallel, they have to have the same slope. In this case, The slope is undefined because it is a straight line. To make a line that has the  points x= -2 and y=9, the line would just be x=-2.

x=-2 also has an undefined slope, so it is parallel. And if the line is straight the point -2,9 will eventually end up on the line.
