There aren't any numbers that add to 24 but multiply to 9. But you can still factorise - remember, you only need to get numbers that add up to the middle number if the coefficient of y^2 is 1. That means if you just have y^2, not 2y^2 or 3y^2 or 16y^2 like we do here.

4x+y=-9
4(k)+3=-9
4k=-12
k=-3
True.
If the clock loses 1 second every hour that passes then after 4 hours it will be 4 seconds off, 5 hours will be 5 seconds off, etc. It would continue and turn into minutes and hours off.
Answer:
y=-2/7x-4/7
Step-by-step explanation:
m=(y2-y1)/(x2-x1)
m=(4-(-2))/(-16-5)
m=(4+2)/(-21)
m=6/-21
m=-6/21
y-y1=m(x-x1)
y-(-2)=-6/21(x-5)
y+2=-6/21x+30/21
y=-6/21x+30/21-2
y=-6/21x+30/21-42/21
y=-6/21x-12/21
simplify
y=-2/7x-4/7
