Question

Which of the following lines is parallel to x = 7?

Answer 1

For this case we have the following line:
 x = 7
 This line is a vertical line whose slope tends to infinity.
 To find a parallel line, we must find a line whose slope also tends to infinity.
 Therefore, we must look for a vertical line.
 The line that is vertical for this case is given by:
 x = 4
 Answer:
 The following line is parallel to x = 7:
 D.) x = 4

Answer 2

The best and most correct answer among the choices provided by your question is the fourth choice or letter D. The equation X = 4 is parallel to the line x = 7 because both only have y-components, therefore they will not intersect with one another.
