Question

What is the location of the midpoint of the segment joining the two data points shown in the figure? A) \((0,2)\) B) \((1.5,0)\) (C) \((1.0,0.25)\) D) \((0.5,1)\)

Short answer

Given the coordinates of the two data points in the figure, apply the midpoint formula \((\frac{x_1 + x_2}{2}, \frac{y_1 + y_2}{2})\), insert the coordinates, and compare the result with the given options.

Step-by-step solution

Determine the coordinates of the two data points

By analyzing the figure, identify the coordinates of both data points.

Use the midpoint formula

To find the midpoint of a segment, use the following midpoint formula: \((\frac{x_1 + x_2}{2}, \frac{y_1 + y_2}{2})\), where \(x_1\) and \(x_2\) are the x-coordinates of the two data points, and \(y_1\) and \(y_2\) are the y-coordinates of the two data points.

Plug in the coordinates

Insert the coordinates from Step 1 into the midpoint formula from Step 2 and solve for the midpoint.

Compare the result

Compare the result from Step 3 against the four given options (A, B, C, and D) to determine which one matches the calculated midpoint of the segment.

Key concepts

Coordinate Geometry

Coordinate geometry, also known as analytic geometry, involves the study of geometry using a coordinate system. This branch of mathematics allows us to graphically represent geometric figures and solve geometry problems by using algebraic equations.

In the context of GED math practice, coordinate geometry is a vital area because it combines algebra and geometry skills, which are essential components of the GED math exam. Understanding how to plot points, read graphs, and utilize formulas in a coordinate plane will not only help students solve problems accurately but also enhance their overall mathematical literacy.

Application in Exercises

When tasked with finding the midpoint of a segment in coordinate geometry, students employ the midpoint formula. This problem-solving tool is representative of how algebraic expressions can simplify complex geometric concepts. In essence, the midpoint is the average of the x-coordinates and the average of the y-coordinates of the segment's endpoints.

GED Math Practice

The General Educational Development (GED) test is a four-subject high school equivalency test that covers math, science, social studies, and reasoning through language arts. In GED math practice, critical thinking and problem-solving skills are emphasized, often requiring the application of formulas and conceptual understanding.

Midpoint Formula in GED Math

In the math portion of the GED, problems related to the midpoint formula are common. Mastery of this formula is crucial as it tests the student's ability to analyze a problem, apply a mathematical concept, and arrive at the correct solution systematically. Practice problems involving the midpoint formula can help solidify the student's command over coordinate geometry topics, eventually preparing them for various question types they might encounter on the test day.

Geometry Problem Solving

Geometry problem solving is a fundamental skill in mathematics, involving logical reasoning, spatial visualization, and applying geometric principles to find solutions. It goes beyond memorizing formulas and requires an understanding of the properties and relationships within geometric figures.

Strategies for Solving Geometry Problems

Effective geometry problem solving strategies include drawing diagrams, identifying known and unknown values, and utilizing key formulas, like the midpoint formula. When approaching a problem, it's essential to break it down into manageable steps, which helps in avoiding common mistakes.

For example, in the exercise at hand, the student must first accurately determine the coordinates of the points involved. Following this, applying the midpoint formula correctly to these coordinates is the crucial step. It's imperative to double-check calculations to ensure that the solution is precise. Such an ordered approach to problem solving aids in tackling geometry questions efficiently.
