How To Find Perpendicular Slope With One Point

If you know the equation of the line in standard form you simply need to divide the coefficient of the y term by the coefficient of the x term to find the slope of a perpendicular line.

How to find perpendicular slope with one point. 2 enter a b and c the coefficients of the the given line defined as follows. Click the blue arrow to submit. The 2 2 is the y intercept. If the slope of the original line is a positive whole number then the slope of the perpendicular line will be a negative fraction.

A line perpendicular to another line will always have an opposite slope. Use the slope intercept form y mx b and substitute in the given point and the new slope to find the intercept b. The equation point slope calculator will find an equation in either slope intercept form or point slope form when given a point and a slope. Write the equation of a line that passes through the point 1 3 and is perpendicular to the line y 3 x 2.

The perpendicular slope will be the opposite reciprocal of the original slope. Perpendicular lines are lines that intersect at right angles. Put this together with the sign change and you get that the slope of a perpendicular line is the negative reciprocal of the slope of the original line and two lines with slopes that are negative reciprocals of each other are perpendicular to each other. Multiply the new slope with the x value.

Yes the slope of this line is 3 4 3 4. Then cancel out the product make it become 0 with either addition or subtraction. Two perpendicular slopes multiplied together will always equal. Enter the point and slope that you want to find the equation for into the editor.

Find the slope of the given line. Convert back to standard form of an equation ax by c. The calculator also has the ability to provide step by step solutions. To give a numerical example of negative reciprocals if the one lines slope is.

You can find the slope of a line perpendicular to this line by using the points and going through y2 y1 x2 x1 y 2 y 1 x 2 x 1 or you can just nab it right out of the slope intercept form. A x b y c 3 press enter. Dont forget to add or subtract the y value too. 1 enter the coordinates of the point through which the line passes.

Find the slope of the perpendicular line using the opposite reciprocal.
