The point-slope form is:
y - y1 = m(x - x1)
where m is the slope and (x1, y1) is a point on the line.
Then, the table is:
Slope point point-slope form
-3 (12,5) y - 5 = -3(x - 12)
6 (4,-5) y - (-5) = 6(x - 4)
y + 5 = 6(x - 4)
3 (-6,-2) y - (-2) = 3(x - (-6))
y + 2 = 3(x + 6)
1/2 (7,-6) y - (-6) = 1/2(x - 7)
y + 6 = 1/2(x - 7)
-3/4 (-8,2) y - 2 = -3/4(x - (-8))
y - 2 = -3/4(x + 8)
