Agrocery store sells a 6 pack of bottled waters for $3.79 a 9 pack for $4.50 and a 12 pack for $6.89 which package cost of these per bottle

Ok, so for the first one, we do 3.79/6 = 0.63 cents.

4.50/9= 0.5cents

6.89/12 =0.57 cents

If you want to check your work, for example, multiply 0.5 by 9 and it should give you 4.50

y = 5x + 17

step-by-step explanation:

a perpendicular line will be the opposite reciprocal slope of the given equation.   the slope given is -1/5 so the opposite reciprocal is 5

find b:

7 = 5 (-2) + b

7 = -10 + b

17 = b

write equation

y = 5x + 17
