Step-by-step explanation:

1.

(y -y1) = m(x -x1)

(6 -8) = m(1 -(-2))

-2 = 3m

m = -2/3

2.

slope = ∆y/∆x

slope = (8 -6)/(-2 -1)

slope = 2/-3

Now to find the full expression let's substitute the values of x and y using the slope:

6 = 1×2/-3 + b

6 = 2/-3 +b

b = 6 - 2/-3

b = 16/3

So the expression is:

y = 2x/-3 + 16/3
