s =

We know that

the equation of the line in standard form is
Ax+By=C

the equation of the line  in the slope-intercept form is
y +1 = 2/3 (x - 8)> y+1=(2/3)x-(16/3)> y-(2/3)x=(-16/3)-1
y-(2/3)x=(-19/3)> multiply by 3> -2x+3y=-19

the answer is
-2x+3y=-19

I verify that the points belong to the given line
for the point (8,-1)
-2*8+3*(-1)=-19> -16-3=-19> -19=-19> is ok

for the point (2,-5)
-2*2+3*(-5)=-19> -4-15=-19> -19=-19> is ok
