Question 681702: perpendicular to the line 8x-7y= 77 containing the points (7,-12)
Answer by ReadingBoosters(3246) (Show Source): You can put this solution on YOUR website!
Starting with 8x-7y=77
Isolate y
8x-7y=77
8x-7y+7y = 77+7y
8x=77+7y
8x - 77 = 77 + 7y - 77
8x - 77 = 7y
...
7y = 8x - 77
y =
...
The slope is
A perpendicular line will have a negative inverse/reciprocal slope of
...
Using point(7,-12)
y--12 = (x-7)
y+12 =
y =
y =
y =
