Mar 23, 2024 · If the lines intersect, identify the point of intersection. Check to make sure it is a solution to both equations. This is the solution to the system. If the lines are parallel, the system has no solution. If the lines are the same, the system has an infinite number of solutions.

- Which of the following statements is not true? Three intersecting lines can share a common point of intersection. Two intersecting lines form two pairs of vertical angles.
- Construct a line that will intersect Line $\overline{AB}$. Label the line and intersection point, then name four angles formed by the two intersecting lines.
- It will be impossible to create four intersecting lines that only share one point of intersection. Prove the statement wrong by constructing a counterexample.
If the lines intersect, identify the point of intersection. This is the solution to the system. If the lines are parallel, the system has no solution. If the lines are the same, the system has an infinite number of solutions. Step 5: Check the solution in both equations.
If there are no points of intersection between all the graphs, then there are no solutions to the system of equations. If we are working with a system of two linear equations, then we know that both equations can be graphed to give straight lines.
What Does the Intersection of Two Lines Represent? When the lines intersect, the point of intersection is the only point that the two graphs have in common. So the coordinates of that point are the solution for the two variables used in the equations.
