Which best describes the relationship between the line that passes through the points (–6, –1) and (–11, 1) and the line that pa
yaroslaw [1]
The two are perpendicular to each other because the two slopes are negative reciprocals

(Y2 - Y1) / (X2 - X1)

First slope:
( 1 - (-1)) / (-11 - (-6))
2/-5

Second slope:
(-13 - (-8)) / (-5 - (-3))
-5/-2 or 5/2

You know when two aliens are perpendicular when you multiply the two slopes and get -1 as the product

-2/5 X 5/2 = -1

Thus the two lines are perpendicular to each other.

Find the equation of a line, in slope-intercept fotm of a line that passes through the point (9,2) and is perpendicular to the l
cricket20 [7]

Considering the definition of perpendicular line, the equation of of perpendicular line is y= -\frac{1}{2}x + \frac{13}{2}.

<h3>Linear equation</h3>

A linear equation o line can be expressed in the form y = mx + b.

where

x and y are coordinates of a point.

m is the slope.

b is the ordinate to the origin and represents the coordinate of the point where the line crosses the y axis.

<h3>Perpendicular line</h3>

Perpendicular lines are lines that intersect at right angles or 90° angles. If you multiply the slopes of two perpendicular lines, you get –1.

<h3>Equation of perpendicular line in this case</h3>

In this case, the line is 2x-y=8. Expressed in the form y = mx + b, you get:

-y=8 - 2x

y= (-2x +8)÷ (-1)

y= 2x -8

If you multiply the slopes of two perpendicular lines, you get –1. In this case, the line has a slope of 2. So:

2× slope perpendicular line= -1

slope perpendicular line= (-1)÷ (2)

<u><em>slope perpendicular line= -</em></u>\frac{1}{2}

So, the perpendicular line has a form of: y= -\frac{1}{2}x + b

The line passes through the point (9, 2). Replacing in the expression for perpendicular line:

2= (-\frac{1}{2})× 9 + b

2=  -\frac{9}{2} + b

2+ \frac{9}{2}= b

<u><em /></u>\frac{13}{2}<u><em>= b</em></u>

Finally, the equation of of perpendicular line is y= -\frac{1}{2}x + \frac{13}{2}.
