If two different lines intersect, they will always intersect at one point.
No, two straight lines can intersect at only one point and that is their point of intersection.
Coplanar lines can intersect an infinite amount of times.
With the information provided, all that can be said is that the slopes are two different real numbers.
It depends on how you define "ways" and how you define "lines" and how you define "intersect" and what kind of geometry you're talking about, but in Euclidean geometry, lines either never intersect, or they intersect at a single point, or they can intersect at all points within the lines.
parralel lines
Two lines that are not coplaner exist on two different planes. These lines do not and will not intersect by simple definition. It is however, when speaking of three or more lines, when the possibility that two or more of them may intersect.
skew lines
Perpendicular lines have to intersect to make a right angle Like this: + Intersecting lines don't have to intersect to make a right angle Like this: X
They are called skew lines. Explanation: In 3 space, parallel lines must never intersect AND must be in the same plane. If they fail to intersect and are in different planes we call them skew lines.
yes they intersect, they can also intersect at different angles, obtuse, right, and obtuse
Lines in the same plane that do not intersect Lines in the same plane that do not intersect Lines in the same plane that do not intersect Lines in the same plane that do not intersect
