Answer:
- y = x
- y = -x
- x = 3
- x = 7
- x = -3
Explanation:
You want to identify the lines among those listed that will intersect the line y = 4.
Parallel lines
The line y = 4 is a horizontal line. Any line of the form y = c, for some constant c (not 4), will be parallel and will not intersect y = 4.
All of the other lines listed will intersect y = 4.
The intersecting lines are ...
- y = x
- y = -x
- x = 3
- x = 7
- x = -3
