Ryan has 1,500 yards of yarn. He wants to knit at least 2 scarves and at least 3 hats. Each scarf requires 300 yards of yarn, and each hat requires 120 yards of yarn. If s represents the number of scarves and h represents the number of hats, which of the following systems of inequalities represents this situation?

A collection of more than one inequality in one or more variables is known as a system of inequalities. Systems of inequalities are helpful when a problem's potential solutions are subject to several constraints, and a variety of potential solutions are required.
¶An infinite number of ordered pair solutions for inequality in the set, each specified by a region in a rectangular coordinate plane. When two inequalities are considered, the collection of simultaneously ordered pair solutions is defined by the intersection of these sets.
¶Systems of inequalities can be solved slightly differently than systems of linear equations because the substitution and elimination methods are not applied. Only the limitations of the inequality signs, ≤, and ≥, are responsible for this.

Which of the following is closest to the equation of the line of best fit shown?
