y%2B2=%28%2810-%28-2%29%29%2F%28-9-3%29%29%28x-3%29

y%2B2=%2812%2F%28-12%29%29%28x-3%29

highlight%28y%2B2=-1%28x-3%29%29--------------point-slope form

x1 y1 x2 y2
-9 10 3 -2

slope m = (y2-y1)/(x2-x1)
( -2 - 10 )/( 3 - -9 )
( -12 / 12 )
m= -1

Plug value of the slope and point ( -9 , 10 ) in
Y = m x + b
10.00 = 9 + b
b= 10.00 - 9
b= 1
So the equation will be
Y = -x + 1
