Does it make sense to draw a line through the pionts

Question

For my math homework cause I don't understand so can you help me 

Answer 1

Depends on what you're trying to do.

 

If the problem states to find the equation of the line that passes through two points, then drawing a line might help you to find the equation, but can be impractical. The point of the exercise would be to use a mathematical means to find the answer.
