If two lines intersect, then they intersect in exactly

two points

one point

one line

one plane

The correct answer is one point.

Step-by-step explanation:

 In geometry, if two lines cross each other, they will do so at an exact point.

Imagine that the lines are formed by thousands of points located next to each other, which makes us see a line, therefore if they cross, they will do so at a single point that will have a coordinate in (x, y) format.

When the two lines are on the same plane, the following situations may occur:

 if they match they have an unlimited number of points in common  if they are different but they have the same slope they are parallel and they do not have points in common if the above does not happen, they have a single point of intersection.

Since it takes her 2 1/2 miles to get to the aquarium from her hotel, you need to subtract the various distances from  this value in order to find how long it took Clara to walk the rest of the way to the aquarium. 

2 1/2 - (1/4+1 3/4)= 2 1/2 - 2= 1/2

Clara must walk 1/2 a mile to get the rest of the way to the aquarium.
