Question

the graph above shows the relationship between the numbers of chocolates bought from store a represented along the x - axis, and the number of chocolates bought from store b represented along the y - axis. which equation could represent this relationship? a. 9x + y = 450 b. x + 9y = 450 c. x + y = 450 d. 9x + 9y = 450

Explanation:

Step1: Identify the intercept - form concept

The equation of a line in standard form is \(Ax + By=C\). In the context of the problem, we assume the total number of chocolates is a constant value. Let \(x\) be the number of chocolates from Store A and \(y\) be the number of chocolates from Store B.

Step2: Analyze the relationship

We know that the sum of chocolates from Store A and Store B is a fixed number. If we assume the total number of chocolates is 450, and the number of chocolates from Store A is \(x\) and from Store B is \(y\), the equation representing the total number of chocolates is \(x + y=450\).

Answer:

C. \(x + y = 450\)
