Answer:
Step-by-step explanation:
For one line to be perpendicular to another, their slopes must multiply to -1. So, we really want the line with slope 
that passes through the point 
.
Recall the point-slope form of a line. If you have a point 
and a slope 
, the line through that point with the given slope is 
. Plugging in our given point and slope gives our line: 
(point-slope form).
We can convert this line to slope-intercept form, the most common form by expanding the right side and adding 
to get 
by itself:
Most likely: the one that is probably the best
equally likely: two or more are equal in value
certainly: this one is absolute it is the answer
I'm not sure if that is supposed to be 7 or -7
If it's -7:
1<2n-5<-7
+5 +5 +5 Add 5 to all parts of the inequality get 2n by itself
6<2n<-2
/2 /2 /2 Divide all parts by 2 to isolate the variable
3
