Question

Please help me find the formula of this table graph thingy

the topic Is graph and direct propotion​

Answer 1

Answer Below/Step-by-step explanation:

Formula : y = kx or y = k/x

Thus since the formula is y = kx then we can substitute:

y = 20

k = ?

x = 200

20 = ? / 200

? = 10

Therefore for the rest of the blank

100/10 = 10

500/10 = 50

1000/10 = 100

So the chart now is:

| Drink (x ml) | 200 | 100 | 500| 1000|

| Sugar (y g) | 20 | 10 | 50 | 100 |

Answer 2

Find the ratio of the given one: 20/200 = 0.1

this means the sugar (y) is 0.1 amount of soda (x)

Multiply the amount of soda by 0.1:

Formula is y = 0.1x
