This means for every 1 can of black paint there are 2 cans of white paint in the mix

Step-by-step explanation:

The constant of proportionality is the gradient of line which can be evaluated as follows;

Gradient = delta y / delta x

Gradient = (y2 – y 1) / (x2 – x1)

We shall pick two points on the line graph in (x,y) format;

(3. 6) and (1, 2)

We evaluate the gradient now be repalivn the points on the formula;

Gradient = (2 – 6) / 1 – 3

Gradient = - 4 / - 2

Gradeint = 2/1 = 2

= 2

This means for every 1 can of black paint there are 2 cans of white paint in the mix
