From the given graph, let's find the slope.

Take two points on the line:

(x1, y1) ==> (10, 4)

(x2, y2) ==> (20, 8)

Apply the sloe formula to find the slope:


m=(y2-y1)/(x2-x1)

Thus, we have:


\begin{gathered} m=(8-4)/(20-10) \\ \\ m=(4)/(10) \\ \\ m=(2)/(5) \end{gathered}

The slope of the line is 2/5.

Since the x-axis of the graph represents the amount of Yellow food colouring in ounce while the y-axis represents the red food colouring, the slope represents the amount of red food colouring needed per ounce of yellow colouring.

For every ounce of yellow food colouring, there is 2/5 ounce of red food colouring.

ANSWER:

Slope = 2/5

For every ounce of yellow food colouring, there is 2/5 ounce of red food colouring.
