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.
To determine if two lines will intersect using their slopes, compare the slopes of the two lines. If the slopes are different, the lines will intersect at one point. If the slopes are the same and the y-intercepts are different, the lines are parallel and will not intersect. If both the slopes and y-intercepts are the same, the lines are coincident and overlap entirely.
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.
When three or more lines intersect, they can form various geometric configurations depending on their arrangement. If all lines intersect at a single point, they are concurrent lines. If they intersect at different points, they may create multiple points of intersection, leading to different shapes, such as triangles or polygons. The nature of the intersection can significantly impact the properties of the resulting figures.
