Intersection of two lines is a point at which both lines meet. When two lines share a common point, they are called intersecting lines. This common point that exists on all intersecting lines is called the point of intersection. The two non-parallel straight lines which are co-planar will have an intersection point.

Point of intersection means the point at which two lines intersect. These two lines are represented by the equation a1x + b1y + c1= 0 and a2x + b2y + c2 = 0, respectively. Given figure illustrate the point of intersection of two lines. We can find the point of intersection of three or more lines also. By solving the two equations, we can find ...
- Find the point of intersection of line 3x + 4y + 5 = 0, 2x + 5y +7 = 0. The point of intersection of two lines is given by : (x, y) = ((b1*c2−b2*c1)/(a1*b2−a2*b1), (c1*a2−c2*a1)/(a1*b2−a2*b1))
- Find the point of intersection of line 9x + 3y + 3 = 0, 4x + 5y + 6 = 0. The point of intersection of two lines is given by : (x,y) = ((b1*c2−b2*c1)/(a1*b2−a2*b1), (c1*a2−c2*a1)/(a1*b2−a2*b1))
- Check if the two lines are parallel or not 2x + 4y + 6 = 0, 4x + 8y + 6 = 0. To check whether the lines are parallel or not we need to check a1/b1 = a2/b2.
- Check if the two lines are parallel or not 3x + 4y + 8 = 0, 4x + 8y + 6 = 0. To check whether the lines are parallel or not we need to check a1/b1 = a2/b2.
Solved Examples. Example 1: Find the point of intersection for the lines 3 x + 2 y − 5 = 0 and 2 x − y + 3 = 0. Solution: Using the method described, let's find the point of intersection for the lines 3 x + 2 y − 5 = 0 and 2 x − y + 3 = 0. First, we identify the coefficients a 1, b 1, c 1, a 2, b 2, and c 2:
The equation of Line 1 1 is y=x+1 y = x + 1 and the equation of Line 2 2 is y=x-5. y = x − 5. The slope of Line 1 1 is 1 1 and the slope of Line 2 2 is 1. 1. Notice how the slopes are the same. Parallel lines will always have the same slope because they will not intersect. Let’s look at another example.

Oct 11, 2024 · We say that two lines in 2D or 3D space are intersecting if they cross each other. The intersecting lines can cross at one point only — this point is called the point of intersection. If two lines have more than one point in common, then these lines coincide (i.e., are the same). It's also possible that two lines do not intersect at all.
