Question

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 is means in the problem situation.

Answer 1

Slope = ⅚

Explanation:

Using the coordinates of two points in the graph, say (0, 0) and (6, 5).

`(y_2 - y_1)/(x_2 - x_1) = (5 - 0)/(6 - 0) = (5)/(6)`

The slope of the graph is ⅚.

The slope represents the ratio of proportion of yellow paint to blue paint that must be mixed together to produce green paint.

This means, to make green paint, for every 5 parts of yellow paint, 6 parts of blue paint is required to be added as a mixture.
