Problem:
(0,-9) slope -2 
:
Use the point/slope equation; y - y1 = m(x - x1)
In this problem
x1 = 0
y1 = -9
m = -2
:
Substitute in the equation
y - (-9) = -2(x - 0)
y + 9 = -2x + 0
y = -2x - 9; this is the equation for the given pair and slope
:
3 additional points 
for x=-2;
y = -2(-2) - 9
y = +4 - 9
y = -5
the ordered pair -2,-5
:
for x=-1; 
y = -2(-1) - 9
y = 2 - 9
y = -7
the ordered pair -1,-7
:
for x=+2
y = -2(2) - 9
y = -4 - 9
y = -13
ordered pair 2,-13</PRE>
