Question

practice

1. the graph shows the proportions of blue paint and yellow paint that briana mixes to make green paint. what is the slope of the line? tell what it means in the problem situation.

Explanation:

Step1: Select two points on the line

Let's take the points (0,0) and (8,8).

Step2: Apply slope - formula

The slope formula is $m=\frac{y_2 - y_1}{x_2 - x_1}$. Here, $x_1 = 0,y_1 = 0,x_2=8,y_2 = 8$. So $m=\frac{8 - 0}{8 - 0}=1$.

Step3: Interpret the slope

The slope of 1 means that for every 1 unit increase in the amount of blue paint, there is a 1 - unit increase in the amount of yellow paint.

Answer:

The slope of the line is 1. It means that for every unit of blue paint, an equal unit of yellow paint is mixed to make green paint.
