Why do some systems of equations have one solution?
If it is a linear system, then it could have either 1 solution, no solutions, or infinite solutions. To understand this, think of two lines (consider a plane which is just 2 dimensional - this represents 2 variables and 2 equations, but the idea can be extended to more dimensions).If the 2 lines intersect at a point, then that point represents a solution. If the lines are parallel, then they never intersect, and there is no solution. If the equations are such that they are just different ways of describing the same line, then they intersect at every point, so there are infinite solutions. If you have more than 2 lines then maybe some of them will intersect, but this is not a solution for the whole system. If all lines intersect at a single point, then that is the single solution for the whole system.If you have equations that describe something other than a straight line, then it's possible that they may intersect in more than one point.
The two lines graphed below are parallel How many solutions are there to the system of equations?
Although there is no graph, the number of solutions is 0.
What are perpedicular lines?
Perpendicular Lines are two or more lines that will intersect (come together) at some point along their paths. Paralell lines are 2 or more lines that will never intersect at any point in their paths.
Two distinct lines that do not intersect are parallel?
2 lines the same width apart are parallel.
How many pairs of parallel sides does a quadrilateral have?
A quadrilateral has 4 sides, 2 in which never intersect. Therefore, the lines that don't intersect are called parallel. There are 4 parallel sides but has 2 pairs of parallel sides.
What are 2 lines that do not and will not intersect?
2 lines that do not and will not intersect are called parallel lines.
Which 2 lines can intersect?
Any 2 lines can intersect providing that they are not parallel lines

How many lines are intersected when two planes intersect?
2
How many angles are formed when 2 lines intersect?
Four
2 lines that will never intersect?
Parallel straight lines never intersect.
Will non parallel lines intersect?
If the 2 lines lie in the same plane, and they are not parallel, then they will intersect at some point. If the 2 lines are skew lines, then they are not in the same plane, and they will not intersect (but they are Not Parallel)
2 lines that do not intersect?
If they are in the same plane, two lines that don't intersect are said to be "parallel".
What are the number of points at which 2 parallel lines intersect?
Zero; parallel lines never intersect.
What defines lines that do not intersect?
Lines don't intersect:- 1) When lines are parallel 2) When lines don't lie on same plane
How many angeles are formed when two lines intersect do not count straight angles 2 4 8?
Four opposite equal angles are formed when 2 lines intersect each other
What are 2 lines in the same plane that never intersect?
Two lines that are in the same plane and never intersect are called "Parallel," meaning that they are lines with the same slope, but not y-intersect.
