Answer:
y=-1/2x-5
Step-by-step explanation:
First we need to put (y-3)=2(x-4) in slope intercept form.
we need to do order of operations....
so we need to first do the parenthesis
x*2= 2x
2*-4= -8
y-3=2x-8
add 3 on both sides to isolate y
y= 2x-5
so now we know the y=mx+b form
this is one line...
now we need to find out what line is perpendicular.
Perpendicular lines have opposite reciprocals slopes.
y=-1/2x-5
If given the equation, you need to take the number beside the x and y and change their signs to get your point:
x - 8 (Take the -8 and make it +8)
y + 2 (Take the +2 and make it -2)
Your point is (8, -2)

Answer:
log 5
Step-by-step explanation:
We can rewrite this by using a property of logs
log a - log b = log (a/b)
log(10) - log(2)
log(10/2)
log 5
