Step-by-step explanation:
7r=-7/2
divide both sides by 7 to get r by itself
(7r)/(7) = (-7/2)/(7)
if you don't quite see it, think of multiplying both sides by 1/7 instead (its the same thing as dividing by 7)
(7r)*(1/7)=(-7/2)*(1/7)
r=-1/2
Pint slope form:
y-y1 = m (x-x1)
Where :
m= slope
y1,x1 = coordinates of a point.
Replacing:
y-9 = -5/8 (x-4)
No, they'd need 13 1/2 quarts of grain. 2 1/4 x 2 for 2 horses = 4 1/2
4 1/2 x 3 for 3 days = 13 1/2
