The equation of Line 1 is y=x and the equation of Line 2 is y=-\cfrac{1}{3} . The point of intersection (common point) is the ordered pair (0, 0). In this next example, the two lines on the coordinate plane do not have any common point of intersection. They are considered to be parallel lines which means they are non-intersecting lines.
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.
- 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.
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 ...

A point of intersection is a point where two lines or curves meet.We can find a point of intersection graphically by graphing the curves on the same graph and identifying their points of intersection.We can find a point of intersection algebraically using the following steps:Sandy has to run errands today in a small town she is staying in for work. She needs to visit the post office, the grocery store, the dog park, the mall, and the hardware store. She is unfamiliar with the area, but she has the following information. 1. If the roads in the town were placed on the same xy-plane, then their equations would be as follo...

Example 2: Identify the pair of lines given below as intersecting lines or non-intersecting lines. Solution: According to the direction of lines, if such lines are extended further, they will meet at one point. Therefore, the given pair of lines are intersecting lines. Example 3: Give any two real-life examples of intersecting lines and non ...

One method to find the point of intersection is to substitute the value for y of the 2 nd equation into the 1 st equation and solve for the x-coordinate. -x + 6 = 3x - 2. -4x = -8. x = 2. Next plug the x-value into either equation to find the y-coordinate for the point of intersection. y = 3×2 - 2 = 6 - 2 = 4. So, the lines intersect at (2, 4).
