Question

(04.03 LC)

Answer 1

Answer:

7 white paints

Step-by-step explanation:

Given

The attached graph

Required

Determine the number of white paints per yellow paints

The interpretation of this question is to determine the slope or rate of the graph.

Represent the yellow paints with x and the white with y

So, we have:

$(x_1,y_1) = (3,21)$

$(x_2,y_2) = (9,63)$

The slope is then calculated as:

$m = \frac{y_2 - y_1}{x_2 - x_1}$

$m = \frac{63- 21}{9 - 3}$

$m = \frac{42}{6}$

$m = 7$

Hence, 7 white paints are needed per 1 yellow paint
