of quarts of yellow paint, y, is represented by the graph below. What is the constant of proportionality as shown in the graph? Amount of yellow paint (in quarts) 5.30) Amount of red paint (in quarts)

Respuesta :

The constant of proportionality refers to the slope of the given line.

Let's use the points (0,0) and (2,9).

We replace these points in the slope formula.

[tex]m=\frac{y_2-y_1}{x_2-x_1}_{}[/tex][tex]m=\frac{9-0}{2-0}=\frac{9}{2}=4.5[/tex]

Therefore, the constant of proportionality is represented by (1, 4.5).
