Answer:
b/a
Step-by-step explanation:
Perpendicular lines have slopes that are opposite sign and reciprocals (flipped over).
In the equation
ax + by = c,
the slope of the line is
-a/b
If you haven't memorized this pattern yet, you can calculate it by solving ax+by=c for y.
by = -ax +c
y = -a/b x + c/b
The slope is -a/b
So a perpendicular line would be opposite sign and flipped, b/a
The answer is C.)
hope this helped :)
no solution
add 4k to both sides of the equation and you have ...
18 = -10 . . . . false
There is no value of k that will make this statement true. There is no solution.
