Find the slope  between the given points

 

[-2 - 7 ] / [-3 - -1 ] =    -9 / -2  =  9/2

 

Since we have a line.....the slope bewtween  any  two points is the same

 

So

 

[y - 7]   / [ -6 - -1 ] =   9/2

 

[y - 7] / -5  = 9/2

 

y - 7  = -5 (9/2)

 

y - 7  = -45/2

 

y = -45/2 + 7  

 

y = -31/2
