Which of the following lines is perpindicular to.
When determining if a two lines are perpindicular, we are only concerned about their slopes. Consider the basic equation of a line, , where m is the slope of the line. Two lines are perpindicular to each other if one slope is the negative and reciprocal of the other.
The first step of this problem is to get it into the form, , which is. Now we know that the slope, m, is. The reciprocal of that is , and the negative of that is. Therefore, any line that has a slope of will be perpindicular to the original line. Which of the following lines is perpendicular to the line with the given equation:?
First we must recognize that the equation is given in slope-intercept form, where is the slope of the line. Two lines are perpendicular if and only if the product of their slopes is. In other words, the slope of a line that is perpendicular to a given line is the negative reciprocal of that slope. Thus, for a line with a given slope of 3, the line perpendicular to that slope must be the negative reciprocal of 3, or. To double check that that does indeed give a product of when multiplied by three simply compute the product:.
Perpendicular lines have slopes whose product is. The slope is controlled by the coefficient, from the genral form of the slope-intercept equation:. Are the following two lines perpendicular:. For two lines to be perpendicular, their slopes have to have a product of.
Find the slopes by the coefficient in front of the. The y-intercept does not matter for determine perpendicularity. Are the lines described by the equations and perpendicular to one another? Why or why not? Yes, because the product of their slopes is not. Yes, because the product of their slopes is. No, because the product of their slopes is not. No, because the product of their slopes is.
If the slopes of two lines can be calculated, an easy way to determine whether they are perpendicular is to multiply their slopes. If the product of the slopes is , then the lines are perpendicular. In this case, the slope of the line is and the slope of the line is. Since , the slopes are not perpendicular. Line , which follows the equation , intersects line at. If line also passes through , are and perpendicular? No, because the product of their slope is not.
The product of perpendicular slopes is always. Knowing this, and seeing that the slope of line is , we know any perpendicular line will have a slope of. Since the two lines AB and CD intersect each other at right angles, there are 4 right angles at the intersecting point. In the following figure, AB is perpendicular to CD.
To find the slope of two lines we use the perpendicular line's formula. The perpendicular line formula is defined as the product of two slopes m1 and m2 is Parallel lines are those lines that do not intersect anywhere and are always the same distance apart.

What is a Perpendicular Line?
Perpendicular Lines and Parallel Lines. Parallel Lines Perpendicular lines Parallel lines are those lines that do not intersect anywhere and are always the same distance apart. Lines that intersect each other forming a right angle are called perpendicular lines. Example: the steps of a straight ladder; the opposite sides of a rectangle.
Examples on Perpendicular Lines Example 1: The two lines inside the kite intersect each other at right angles are perpendicular. Solution Since the two lines AB and CD intersect each other at right angles, there are 4 right angles at the intersecting point.
