I think the 4th one but Im not too sure please forgive me if I'm wrong.
In form
ax+by=c
slope=-a/b
y intercpept=c/b
so
-3x-4y=-12
a=-3
b=-4
c=-12
slope=-(-3)/-4=3/-4=-3/4
yint=-12/-4=3
slope=-3/4
yint is 3
Here is the answer
I can’t seem to do the symbols here so the answer is in the picture.
They ran the same amount of miles, because the zero at the end doesn't count.
