In classical or Euclidean plane geometry two points defines exactly one line. On a sphere two points can define infinitely many lines only one of which will represent the shortest distance between the points. On other curved surfaces, or in non-Euclidean geometries, the number of lines determined by two points can vary.
Even in the Euclidean plane, two points determine infinitely many lines that are not straight!

Points a b c and d are coplanar b c and d are collinear not a how many lines are determined by a b c and d?

If two lines have different slopes and different y intercepts how many points of intersection are there?
If two lines have different slopes, then they intersect at exactly one point. It makes no difference what their y-intercepts are.
How many lines can you draw through two points?
one
How many lines can be drawn through 2 points?
1 straight line. An infinite number of curved lines.
How many lines can pass through two given points?
Just one.
How many different lines are determined by three non-collinear points?
3
How many different lines are determined by three collinear points?
As long as at least two of them are different points, exactly one line.
How many lines are determined by A B and C?
Three lines are determined by three points unless the points are all on the same line ( i.e. co-linear)
How many different lines are determined by 3 non collinear points?
Any three non-collinear points will define a single plane. A plane is composed of an infinite number of distinct lines.
How many different planes are determined by three nonlinear points or by two intersecting lines?
Exactly one plane in each case.

How many different lines can be drawn using 6 points if no 3 of which are collinear?
15 lines.
How many different lines can be formed by three non-collinear points?

How many different lines can you draw through a set of two points?
Since the question does not require them to be straight lines, the answer is infinitely many.
