**Which Ordered Pairs are in the Solution Set of the System of Linear Inequalities?**

In this article, we will explore the concept of systems of linear inequalities and determine which ordered pairs are in the solution set of the given system. We will use the method of graphing to visualize the solution set and identify the ordered pairs that satisfy both inequalities.

Understanding Systems of Linear Inequalities

A system of linear inequalities is a set of two or more linear inequalities that are combined to form a single system. Each inequality in the system is in the form of ax + by ≤ c, where a, b, and c are constants, and x and y are variables. The solution set of a system of linear inequalities is the set of all points that satisfy both inequalities.

Graphing the Inequalities

To graph the inequalities, we will use the slope-intercept form of a linear equation, which is y = mx + b, where m is the slope and b is the y-intercept. The inequality y ≥ -1/3x + 2 can be graphed by drawing a line with a slope of -1/3 and a y-intercept of 2. The inequality y < 2x + 3 can be graphed by drawing a line with a slope of 2 and a y-intercept of 3.

Graphing the First Inequality

The first inequality is y ≥ -1/3x + 2. To graph this inequality, we will draw a line with a slope of -1/3 and a y-intercept of 2.

# Graph of the First Inequality

## Equation: y = -1/3x + 2

## Graph:

The graph of the first inequality is a line with a slope of -1/3 and a y-intercept of 2. The inequality is satisfied by all points on or above this line.

Graphing the Second Inequality

The second inequality is y < 2x + 3. To graph this inequality, we will draw a line with a slope of 2 and a y-intercept of 3.

# Graph of the Second Inequality

## Equation: y = 2x + 3

## Graph:

The graph of the second inequality is a line with a slope of 2 and a y-intercept of 3. The inequality is satisfied by all points below this line.

Finding the Solution Set

To find the solution set of the system of linear inequalities, we need to find the points that satisfy both inequalities. We can do this by finding the intersection of the two graphs.

# Intersection of the Two Graphs

## The intersection of the two graphs is the solution set of the system of linear inequalities.

The solution set of the system of linear inequalities is the set of all points that satisfy both inequalities. We can find the solution set by finding the intersection of the two graphs.

Determining the Ordered Pairs

To determine which ordered pairs are in the solution set, we need to find the points that satisfy both inequalities. We can do this by plugging in the values of x and y into both inequalities and checking if they are satisfied.
