Jen has a map of a local park that is represented on a coordinate grid. There are several paths for walking and bicycling that extend the entire length of the park. Jen is walking on a path that is represented on the map as a line with the equation y = 2x + 5. Her friend Dave is on a bike path that is represented on the map as a line with the equation y = 0.5x + 6.5. Which statement about Jen's path and Dave's path is true?

• The two paths will intersect at two different points.

• The two paths will never intersect.

• The two paths are the same.

• The two paths will intersect at one point.
