(i) Intersecting lines (ii) Parallel lines (iii) Coincident lines. Solutions: (i) Given the linear equation 2x + 3y - 8 = 0. To find another linear equation in two variables such that the geometrical representation of the pair so formed is intersecting lines, it should satisfy below condition; (a1/a2) ≠ (b1/b2 Obtain the condition for two lines to be intersecting, parallel or coincident from the observation table by comparing the values of . Observation Students will observe that. for intersecting lines, for parallel lines, for coincident lines, Result The conditions for consistency of a system of linear equations in two variables is verified. Intersecting lines; Non-intersecting lines; Intersecting Lines. Two or more lines which share exactly one common point are called intersecting lines. This common point exists on all these lines and is called the point of intersection. It is to be noted that: The intersecting lines meet at one, and only one point, no matter at what angle they meet 4. Observe if the lines are intersecting, parallel or coincident and note the following 5. Take the second pair of linear equations in two variables, e.g. 6x + 10y = 4, 3x + 5y = 2 6.

Here, lines P and Q intersect at point O, which is the point of intersection. In the given image below, there are many straight lines crossing each other and intersecting at the common point P. Properties of intersecting lines. The intersecting lines (two or more) meet only at one point always. The intersecting lines can cross each other at any. ** Class 10**. PRMO NTSE But in case of intersecting lines, there are only two lines, line segments or rays meet each other at one common point. These lines are considered as concurrent if the below -given conditions hold true. Ih have three straight lines with L₁ = 0,. The lines which coincide or lie on top of each other are called coincident lines. You may have learned about different types of lines in Geometry, such as parallel lines, perpendicular lines, with respect to a two-dimensional or three-dimensional plane.. In the case of parallel lines, they are parallel to each other and have a defined distance between them This video is on behaviour of lines representing a pair of linear equations in two variables and the existence of solutions of class 10th math chapter 3 Pai..

- The points where the two lines intersect are called the solutions of the pair of linear equations. Condition 1: Intersecting Lines If a1/a2 ≠ b1/b2, then the pairof linearequationsa1x+ b1y + c1 = 0, a2x+ b2y + c2 = 0 has a uniquesolution
- To find the intersection of two straight lines: First we need the equations of the two lines. If you do not have the equations, see Equation of a line - slope/intercept form and Equation of a line - point/slope form (If one of the lines is vertical, see the section below). Then, since at the point of intersection, the two equations will have the same values of x and y, we set the two equations.

Then by given condition. 14 Step 3: Draw a line representing the equation x+2y = 3 on graph paper I by plotting the points (1,1) and (3,0), and joining them. Similarly, draw a line representing the equation 4x + 3y = 2 by plotting the points (-1, 2) and (2, -2), and joining them. Step 4: Record your observations in the first observation table. Step 5: Consider a second system of linear equations An intersection of two lines is a point where the graphs of two lines cross each other. Every pair of lines does have an intersection, except if the lines are parallel. This means that the lines move in the same direction. You can check whether two lines are parallel by determining their slope. If the slopes are equal, then the lines are parallel So, the lines intersect at (2, 4). Intersecting lines and angles. Angles are formed when two or more lines intersect. In the figure above, MP and NQ intersect at point O forming four angles that have their vertices at O. Vertical angles are congruent so, ∠MOQ≅∠NOP and ∠MON≅∠QOP

The point of intersection of a line and the x-axis is called the x-intercept. Example: Here, s is the x-intercept of line AB. Y-intercept.
