You can use two separate points from one line to find the equation of a line that runs perpendicular to it. Before you calculate the equation of the perpendicular line you will need to find the slope of the line that crosses the two points. The equation for finding the slope of a line with two points is. Equation of a Line Perpendicular to Another Line and Through a point P The slope m of line L given by the equation A x B y C is given by m A B If two lines are perpendicular the product of their slopes is equal to -1.
We need to find to directional vectors that lie in the plane and one point that is in the plane.
One directional vector is P1P2. P1P2 Since the desired plane is perpendicular to the given plane the normal vector n1 of the given plane is also a directional vector of the desired plane. N1. Graph the two equations and measure one of the angles that forms.
According to the definition of a perpendicular line all four angles have to measure 90 degrees.
If the lines are horizontal and vertical then they are perpendicular due to the squares of the coordinate grid. Perpendicular lines have opposite-reciprocal slopes so the slope of the line we want to find is 12. Plugging in the point given into the equation y 12x b and solving for b we get b 6. Thus the equation of the line is y ½x 6.
Rearranged it is x2 y 6.
You can use this calculator to solve the problems where you need to find the line equation that passes through the two points with given coordinates. Enter coordinates of the first and second points and the calculator shows both parametric and symmetric line equations. As usual you can find the theory and formulas below the calculator. Download free worksheetpdf on finding the equation of a line perpendicular to another line and through a given point includes model problems worked out step by step and video tutorial.
The equation of a line is typically written as ymxb where m is the slope and b is the y-intercept.
If you know two points that a line passes through this page will show you how to find the equation of the line. Ex 102 10 Find the equation of the line passing through 3 5 and perpendicular to the line through the points 2 5 and 3 6. Let AB be the line passing through -3 5 perpendicular to the line CD through 2 5 and 3 6 Let Slope of AB m1 Slope of CD m2 Now Line. Perpendicular lines have opposite-reciprocal slopes so the slope of the line we want to find is 12.
Plugging in the point given into the equation y 12x b and solving for b we get b 6.
Thus the equation of the line is y ½x 6. Rearranged it is x2 y 6. Example 17 Find the equation of a line perpendicular to the line x 2y 3 0 and passing through the point 1 2.
