Intersection of Two Linear Polynomials
The intersection of two linear graphs is the point where the two lines meet. Algebraically, it represents the common solution of the two linear equations.
Practice This ConceptMain explanation
Teacher explanation
When two straight lines meet at one point, the coordinates of that point satisfy both equations. Solving the pair of equations gives the same ordered pair as the intersection point on the graph. This connects algebraic solving with graphical meaning.
Example
The lines x + y = 6 and x - y = 2 intersect at (4, 2) because 4 + 2 = 6 and 4 - 2 = 2.
Simple analogy
Where lines meet, equations agree.
Common confusion
Students sometimes read the crossing point from the graph but forget to write it as an ordered pair.
Exam tip
Always verify the intersection point in both equations, especially if the graph scale is small.
