The first way is to solve for the equation of a line with one x y displaystyle xy point and the equation of a line that runs perpendicular to it. X4 The line that is perpendicular to y-3 is a horizontal line because horizontal and vertical lines x- and y- axes for example are perpendicular.
Therefore this line will take the form xn where n is the x-coordinate of the point passed through.
The x-coordinate of the given ordered pair 4-6 is 4 so the equation must be x4. You get y -2x 5 so the slope is 2. 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. The answer is an equation in slope intercept form of the line perpendicular to the line entered and passing through the point entered. The coordinates and coefficients may be entered as fractions integers or decimalssee examples below. Find the Perpendicular Line y-2 -57 Use the slope-intercept form to find the slope.
Tap for more steps.
The slope-intercept form is where is the slope and is the y-intercept. Using the slope-intercept form the slope is. The perpendicular line is vertical and the slope is undefined. Find the equation of a line parallel to y-3 passing through the coordinate 26 What am I suppose to use as the slope.
I m confused on how to answer this in ymxb form.
Example 17 Find the equation of a line perpendicular to the line x 2y 3 0 and passing through the point 1 2. Let equation of line AB be x 2y 3 0 And let point P be P1-2 Let line CD be perpendicular to line AB passing through point P1-2 Lets first calculate slope of line AB x 2y 3 0 2y x 3 2y x 3 2y x 3 y 32 y x2 32 y 12 x 32. Find Any Equation Perpendicular to the Line y3x-6. Choose a point that the perpendicular line will pass through.
Use the slope-intercept form to find the slope.
Tap for more steps. The slope-intercept form is where is the slope and is the y-intercept. Using the slope-intercept form the slope is. 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. In the figure above clearly the line L is perpendicular to y-axis and passing through 0 k on y- axis. Hence the equation of a line perpendicular to y axis is. If the line is passing through some other value on y axis we have to replace k by that value.
The vertical line is parallel to the y-axis and represents a constant value of x.
Since the point is given as they always are in the x y format the point 4 5 has an x-value of 4. And the vertical line through that point will have its x-value as 4 everywhere. Is the equation of the vertical line that passes through the point. This video provides an example of how to find the equation of a line that is perpendicular to a given line in slope-intercept form passing through a given p.
Learn how to write the equation of a line that is perpendicular to a given line.
The equation of a line is such that its highest exponent on its variable. 6 y 3 x 5 Divide both sides by 6 y 6 3 x 6 5 y 2 1 x 6 5 The slope of our first line is equal to 2 1. Perpendicular lines have negative reciprocal slopes so if the slope of one is x the slope of the other is x 1. The negative reciprocal of 2 1 is equal to 2 therefore 2 is the slope of our line.
Find the equation of a line that is perpendicular to line g that contains P Q.
Coordinate plane with line g that passes through the points negative 2 comma 6 and negative 3 comma 2 4x y Q 4P x 4y 4Q P 4x y Q 4P x 4y 4Q P. Find an equation of the line that passes through the point 0 - 3 and is perpendicular to the line - x y 2. Solution to Question 6 Let m 1 be the slope of the line whose equation is to be found and m 2 the slope of the given line.
