The cost of a pack of chewing gum in a vending machine is $0.75. The cost of a bottle of juice in the same machine is $1.25. Julia has $22.00 to spend on chewing gum and bottles of juice for her team and she must buy seven packs of chewing gum. If b represents the number of bottles of juice, which inequality represents the number of bottles she can buy?

• $0.75b\ +\ 1.25\left(7\right)\ge22$

• $0.75b\ +\ 1.25\left(7\right)\le22$

• $0.75\left(7\right)+1.25\left(b\right)\ge22$

• $0.75\left(7\right)+1.25\ \left(b\right)\le22$

What is an equation of the line that passes through the point (4, -6) and has a slope of -3?

• y = -3x + 6

• y = -3x - 6
