A line passes the points (1,7) and (0,3)what is the equation in the slope intercept form

Of four points are collinear, they are also coplanar

If the graphs of the linear equations in a system are parallel, what does that mean about the possible solution(s) of the system? a. there are infinitely many solutions. b. there is no solution. c. there is exactly one solution. d. the lines in a system cannot be parallel.

Two lines that do not intersect are skew. always sometimes or never
