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).
How to Find Intersection of Two Lines? To find the point of intersection of two lines: Get the two equations for the lines into slope-intercept form. That is, have them in this form: y = mx + b. Set the two equations for y equal to each other. Solve for x. This will be the x-coordinate for the point of intersection.
Here you will learn about intersecting lines, including how to find the point of intersection of two straight lines and how to solve simultaneous equations graphically and algebraically.
This online calculator finds and displays the point of intersection of two lines given by their equations.
Dec 11, 2023 · To find the intersection between two lines y = ax + b and y = cx + d the first step that must be done is to set ax + b equal to cx + d. Then solve this equation for x. This will be the x coordinate of the intersection point.
