Answer:
8
Step-by-step explanation:
The ratio of white paint to blue paint in the mix is ...
40% : 20% = 2 : 1
We can multiply this ratio by 4 cups to find ...
white : blue = 8 cups : 4 cups
There are 8 cups of white paint in the mixture.

Answer:
y = 9x-8
Step-by-step explanation:
Find y values for x= -3 and x = 3. These will come out to -35 and 19 respectively.
Plug these numbers into the rise/run equation for slope m (y2-y1)/ (x2-x1). Plugging values in and simplifying you will get 54/6, which reduces to 9. This is your m value.
Apply your m value to x = 3 going backwards (x = 2 gives a y value of 10, 1 gives 1, and 0 gives -8). This will give you a y intercept of -8. This is your b value.
Plug the slope and y intercept into the mx + b equation. This will give you y = 9x-8.
There you go!
