[ y  - - 2] / [ 6 -1] =  -7/4

 

[y + 2 ] = -(7/4) (5)

 

y + 2 = - 35/4

 

y =  -35/4 - 2

 

y = -43/4

We can find the slope of the line to find y.

 

First, we us points A and B to find the slope. 

 

Finding the slope, we have \(5-(-2)\over{-3-1 } \) which is equal to \(-{7\over4}\)

Then, applying the point slope formula, we get \(y-1=-{7\over4}(6+2)\).

Simplifying we get \(y=-13\)

 

Therefore, y = -13.
