Perpendicular = opposite sign and reciprocal slope
Make equation y= mx + b
3x + 4y = 24
4y = -3x + 24
y = -3/4x + 6
Now make slope perpendicular
Slope = 4/3
The answer would be B.

Or, if that hyphen between the lower index and 3 is actually a negative sign, then the sum is -189.
Answer:
A,B,D
Step-by-step explanation:
I just did it .
6n-2+28-14n if you distribute it
The correct answers are :
x + y = -1
x + 4y = 0
8x - 3y = 20
