Answer:
B
Step-by-step explanation:
- First find the perdendicular slope (flip and change sign) : m= -
- Then set up your equation using the given ordered paired to find your y-intersept: -1 = -
(5) + b
- Caluclate the product: -1 = -
+ b
- Move the variable to the left-hand side and change its sign : -b - 1 = -
- Calculate the sum: -b = -
- Change the sign : b=
- Use the slope and y-intersept to creat the equation: y = -
