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

Step-by-step explanation:
8/4 = 2 so each bulb costs $2
To find how many bulbs you can buy with $32, divide 32 by 2 = 16
20 - 4x = 2(4 - 8x)
Make sure to do the parentheses first or factor out first
20 - 4x = 8 - 16x
add 16x to both sides
20 + 12x = 8
Subtract 20
12x = -12
Divide by 8
x = -1
