Anybody knows the answer real quick

Answer:
I think it's 3
Step-by-step explanation:
To calculate the gradient equals to
y(1)-y(2)
-----------
x(1)-x(2)
So - 5 - 1 = - 6
6 - 2 = 4
-6 - 3
--- = ----- x
4 2
And the first y intercept is 1 so I guess it's 3.
Just for refernece, not sure if I'm correct. Sry
Answer:
Number 2 is the answer.
Step-by-step explanation:
Use the formula: y - y1 = m(x - x1)
y - 1 = -3/2(x - 2)
y - 1 = -3/2x + 3
+1 +1
y = -3/2x + 4
