Question

What is the equation of the line perpendicular to 2x – 3y = 13 that passes through the point (–6, 5)?

Answer 1

-3/x -4
Work:
turn 2x -3y = 13 to 2/3x -13/3.
flip 2/3x to 3/2x and change the positive sign to a negative
y = -3/2x
plug -6 into x and 5 into y
you get 5= 9
then subtract 4 from 9 to get 5 = 5.

Answer 2

Answer: The require equation of the line is
`3x+2y+8=0.`

Step-by-step explanation: We are given to find the equation of the line perpendicular to the following line that passes through the point (–6, 5) :

`2x-3y=13~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~(i)`

We know that

the equation of a line in slope-intercept form is given by

`y=mx+c,`

where m is the slope of the line.

From equation (i), we have

`2x-3y=13\\\\\Rightarrow 3y=2x-13\\\\\Rightarrow y=(2)/(3)x-(13)/(3).`

So, the slope of the line (i) is

`m=(2)/(3).`

Let m' be the slope of the line that is perpendicular to line (i).

Since the product of the slopes of two perpendicular lines is -1, so we must have

`m* m'=-1\\\\\Rightarrow (2)/(3)* m'=-1\\\\\Rightarrow m'=-(3)/(2).`

Since the line passes through the point (-6, 5), so its equation will be

`y-5=m'(x-(-6))\\\\\\\Rightarrow y-5=-(3)/(2)(x+6)\\\\\Rightarrow 2y-10=-3x-18\\\\\Rightarrow 3x+2y+8=0.`

Thus, the required equation of the line is
`3x+2y+8=0.`
