Yes it is a square number
It's subtraction or multiplacation
I think its 8m/h or somethan but idrk. Like it doesnt specify how long it took him the run the 2 hours so idrk. Or it would be 2m/d + 6m/h with d=day
First, set up the equation using the point-slope formula (y-y1)=m(x-x1).
y1=-4 x1=-3 m=-7/2
(y+4)=-7/2(x+3)
Second, distribute -7/2.
(y+4)=(-7/2)x - 21/2
Third, subtract 4 from both sides.
(y+4)=(-7/2)x - 21/2
-4 -4
______________
y=(-7/2)x - 29/2
