Question

mr. garcia orders luminary bags, which are small paper lanterns, to decorate his sidewalk for a holiday celebration. the graph shows the relationship between the number of luminary bags ordered and the total cost. which equation represents the total cost, $ y $, of $ x $ luminary bags?
options: $ y = 0.50x $, $ y = 2x $, $ y = x + 2 $, $ y = x + 0.50 $

Explanation:

Step1: Identify slope from graph

Take two points, e.g., (10, 5) and (20, 10). Slope $m = \frac{10 - 5}{20 - 10} = \frac{5}{10} = 0.5$.

Step2: Determine equation form

The linear equation is $y = mx + b$. Since when $x = 0$, $y = 0$ (b=0), so $y = 0.5x$.

Answer:

$y = 0.50x$ (the first option)
