Line v passes through point [6.6] and is perpendicular to the graph of y= 3/4x - 11 line w is parallel to line v and passes thro

lbvjy [14]

Given:

The equation of a line is

$y=\dfrac{3}{4}x-11$

Line v passes through point (6,6) and it is perpendicular to the given line.

Line w passes through point (-6,10) and it is parallel to the line v.

To find:

The equation in slope intercept form of line w.

Solution:

Slope intercept form of a line is

$y=mx+b$ ...(i)

where, m is slope and b is y-intercept.

We have,

$y=\dfrac{3}{4}x-11$ ...(ii)

On comparing (i) and (ii), we get

$m=\dfrac{3}{4}$

So, slope of given line is $\dfrac{3}{4}$ .

Product of slopes of two perpendicular lines is -1.

$m_1\times m_2=-1$

$\dfrac{3}{4}\times m_2=-1$

$m_2=-\dfrac{4}{3}$

Line w is perpendicular to the given line. So, the slope of line w is $-\dfrac{4}{3}$ .

Slopes of parallel line are equal.

Line v is parallel to line w. So, slope of line v is also $-\dfrac{4}{3}$ .

Slope of line v is $-\dfrac{4}{3}$ and it passes thorugh (-6,10). So, the equation of line v is

$y-y_1=m(x-x_1)$

where, m is slope.

$y-10=-\dfrac{4}{3}(x-(-6))$

$y-10=-\dfrac{4}{3}(x+6)$

$y-10=-\dfrac{4}{3}x-\dfrac{4}{3}(6)$

$y-10=-\dfrac{4}{3}x-8$

Adding 10 on both sides, we get

$y=-\dfrac{4}{3}x-8+10$

$y=-\dfrac{4}{3}x+2$

Therefore the equation of line v is $y=-\dfrac{4}{3}x+2$ .

3x + 2y + z = 8 2x - 3y + 2z = -16 x + 4y - z = 20

padilas [110]

I'll do a similar problem, and I challenge you to do this on your own using similar methods!

x+5y+2z=23
8x+4y+3z=12
9x-3y-7z=-10

Multiplying the first equation by -8 and adding it to the second one (to get rid of the x) and also multiplying the first equation by -9 and adding the third one to get rid of the x there too, we end up with

-36y-13z=-92
and
-48y-25z=-217

Multiplying both equations by -1, we get
36y+13z=-92
48y+25z=217

Multiplying the (new) first equation by -4/3 and adding it to the second (to get rid of the y), we get
(7+2/3)z=94+1/3

Dividing both sides by (7+2/3) to separate the z, we get
z= $\frac{282/3}{23/3} = \frac{282}{23}$

Plugging that into
48y+25z=217, we can subtract 25z from both sides and divide by 48 to get
$y= \frac{217-25z}{48} =\frac{217-25*282/23}{48}$

Lastly, we plug this into x+5y+2z=23 to get
x=23-5y-2z by subtracting 5y+2z from both sides to get
$x=23- \frac{217-25*282/23}{48}*5-2*282/23$

Good luck, and feel free to ask with any questions!
