One third = two sixths
1/6 + 1/6 = 1/3
Point slope form: y1-y2=m(x1-x2)
Given the slope -4 and the set of coordinates (4,-9),
y+9=-4(x-4)
I plugged in the slope and coordinates. Since -9 came after a subtraction sign, I corrected the subtraction to addition, leaving the above point slope form equation.
I hope this helps :)
