When given the equation of a line in slope-intercept form, y=mx+b, where m=slope, simply take the negative reciprocal of m to find the slope of a perpendicular line. The slope of the perpendicular line is -1/m.How To Find Perpendicular Lines Using Algebra Negative Reciprocal of Slopes:...
We know that a straight line is a curve such that every point on the line segment joining any two points on it lies on it. Also, the trigonometrical tangent of the angle that a line makes with the positive direction of the x-axis in an anticlockwise sense is called the slope or the ...

The equation of a plane in 3d space is defined with normal vector ( perpendicular to the plane ) and a known point on the plane . 平面上的一点以及垂直于该平面的法线唯一定义了3d空间的一个平面。 Each of the main lines of trenches was connected to each other and to the rear by a series...
Write an equation of the line that passes through (3, -4) and is perpendicular to the line y = 2x + 5 Perpendicular Lines: Given two lines that intersect one another, for both lines to maintain mutual perpendicularity, one line's slope must be equal...
algebraically. You must know the structure of a straight-line equation before you can write equations for parallel or perpendicular lines. The standard form of the equation is "y = mx + b," in which "m" is the slope of the line and "b" is the point where the line crosses the y-...
Substituting these values in equation ( 1) we will get, y + 90o+ 30o= 180o ⇒ y + 120o= 180o ⇒ y = 180o– 120o ⇒ y = 60o Now, let us consider ∆ AC. Again, we will use that property that the sum of the measure of the three interior angles of a triangle is ...
