9. What is the equation in standard form of the line which passes through (-2, 6) and has a slope of -1? (5 points) O x + y = -4 O x + y = 4 O x - y = -4 O x - y = 4​

Step-by-step explanation:

(-2 , 6)

Slope = m = -1

y =mx + b

y = -x +b

Plugin x = -2 and y = 6

6 = -(-2) + b

6 = 2 + b

6-2 = b

b = 4

y = -x + 4

x + y = 4
