Line k passes through points (-3,-6) and (-1,12) what is the slope of the line perpendicular to line c

1 answer:

4 0

Do you mean "perpendicular to k"? We have no line c there so I'm going with line k. First we need the slope of line k. Fitting those values into the slope formula we have $m= \frac{12-(-6)}{-1-(-3)} = \frac{18}{2} =9$ . So the slope of k is 9. The slope of a line perpendicular to k has the opposite sign and the fraction is flipped. The perpendicular slope then is -1/9.

In the form of the matrice, how do you work out the following simultaneous equation?

lapo4ka [179]

$\left[\begin{array}{ccc}1&3&7\\1&1&1\end{array}\right]$
multiply 2nd row by -1 and add to first row
$\left[\begin{array}{ccc}0&2&6\\1&1&1\end{array}\right]$
divide the 1st row by 2
$\left[\begin{array}{ccc}0&1&3\\1&1&1\end{array}\right]$
multiply the first row by -1 and add to 2nd row
$\left[\begin{array}{ccc}0&1&3\\1&0&-2\end{array}\right]$

now we know
y+3=0
x-2=0

therefor
y=-3
x=2
