Question

2. Perpendicular to y=1/2x -6 that passes through (6,-4) PLEASE HELP ME ASAP

Answer 1

Answer:

To get the slope (which we'll call n) of a line perpendicular to another line with slope (a/b), use

$n = \frac{-b}{a}$

Then we just plug in the point we want to cross and solve for the constant.

Step-by-step explanation:

we see that m = $\frac{1}{2}$

so, $n = -\frac{2}{1} = -2$

now we have the equation

$-2x + b = y$

plugging in (6, -4) we get

$-2(6) + b = -4\\-12+b = 4\\b=4+12=16$

This gives us our function

$y = -2x + 16$
