I can't get to either of these two sites.

I have avastI to protect my computer from viruses; avast tells me that they abort my attempt because of a possible threat.

Two points on line A  =  (3, 7)  and ( 1,1)

 

Slope  =  [ 1 - 7] / [ 1 - 3 ]  =  -6 / -2  =  3

 

Two points on lne B  =  (0,5)  and (1,1)

 

Slope  =  [ 1 - 5 ] / [ 1 - 0]    =  -4/1  =   -4

Second one

 

Two points  on Line A  (2,10)  and  ( 1,1)

Slope =  (1-10) / (1 -2) =  -9/ -1    = 9

 

Two points on Line B = (2,0)  and (0,8)

Slope =  ( 8 - 0) / (0 - 2)  =  8/-2   =  -4
