Question

Which statement best shows the difference between a line and a point?
A point has no dimension but a line has length as a dimension to measure.

A line and a point cannot be collinear.

A point has no location but a line can lie on a plane.

A line has width and depth but a point has only length as a dimension to measure.

Answer 1

hint :
point : no dimension
line : 1 dimension
plane : 2 dimensions

Answer 2

its the last one

Answer 3

...Well, a point on a graph is just some set of coordinates like (0,0), so it does have a location (that rules out answer B). since a point has no length, width, or depth it is a 0 dimensional object. A line has only length so it is 1 dimensional (that rules out D). The term "collinear" means on the same line, and since you can put a point on a line answer A is just plain wrong
i.e. (0,0) is on the line y=x. That leaves C as your only choice...
