Answer 1

The equation that represents the relationship between the red paint and white paint used is

`y = (2)/(3) x`

Linear graph equation is represented by the equation ; y = mx + c

where m is the slope and c is the y intercept.

The slope of the graph shown above is

m = (y₂-y₁)/ (x₂-x₁)

m = 2-0/(3-0)

m = 2/3

therefore the slope of the graph is 2/3

The y intercept is 0 because the line graph intercept the y axis at 0

Therefore, the equation of the relationship is

`y = (2)/(3) x + 0 \\ y = (2)/(3) x`
