Answer 1

Multiply the amount of milk by 4

Explanation:

Given

See attachment for graph

The rule of the graph

Pick any two points on the graph

`(x_1,y_1) = (0,0)`

`(x_2,y_2) = (1,4)`

Calculate slope (m)

`m = (y_2 - y_1)/(x_2 - x_1)`

`m = (4 - 0)/(1 - 0)`

`m = (4)/(1)`

`m =4`

The graph equation is:

`y = m(x - x_1) + y_1`

`y = 4(x - 0) + 0`

`y = 4(x)`

`y = 4x`

The above shows that the x values are multiplied by 4 to get y
