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 ...
Solve for x. This will be the x-coordinate for the point of intersection. Use this x-coordinate and substitute it into either of the original equations for the lines and solve for y. This will be the y-coordinate of the point of intersection. You now have the x-coordinate and y-coordinate for the point of intersection.
Example 1: finding the point of intersection using a graph. Find the point of intersection of the lines y=x+4 and y=2x-3. Plot the graph of the first equation. First plot a graph of the equation y=x+4. Draw a table of values (3 or 4 points are sufficient). 2 On the same set of axes, plot the graph of the second equation.
May 10, 2021 · Find all points of intersection of \(x-4=y^2\) and \(x^2-4x=-y^2\). Solution Here we can see that the only “easy” place to start by solving would be to solve for \(x\) in the first equation, but once we substitute into the second equation, things will get messy quickly.
Example 1: finding the point of intersection using a graph. Find the point of intersection of the lines y=x+4 y = x + 4 and y=2x-3. y = 2x − 3. Plot the graph of the first equation. First plot a graph of the equation y=x+4. y = x + 4. Draw a table of values ( 3 3 or 4 4 points are sufficient). x.
