Bob bought 16 packs of cola. Each pack had 8 cans. He drank 9 of the cans. How many cans are left?
grin007 [14]

Answer:

119 Cans Left

Step-by-step explanation:

If bob brought 16 packs of soda, and each pack had 8 cans, there would be 128 cans. This is because 1 pack is worth 8 cans.

16 × 8 = 128

128 - 9 = 119

Bob drank 9 of the cans, which is the same as subtracting from 128. This gives us the answer.

Answer:

y = 3x - 5

Step-by-step explanation:

So first take any two points from the graph.

(0, -5), (2, 1)

The slope is \frac{1 + 5}{2 - 0} =3

y = mx + b

b is the y intercept

The y intercept is (0, -5) as this is where the line intersects the y axis.

y = 3x - 5
