This is a LearningCheck document that review systems of equations. It involves vocabulary such as consistent and independent, as well as various methods for finding a solution.

A function is a relation that assigns exactly one value of the dependent variable to each value of the independent variable. When a function is graphed, a vertical line can pass through the graph and touch only one point.

In this activity students will explore scatterplots and independent and dependent variables. Students will find the mean value of the number of students applying under the early decision plan.

Using the USA TODAY Infograph, "More students apply early," students will explore scatter plots and independent and dependent variables. Students will determine a best-fit regression model for the real-life data set and then use the...

A reprinting of the Constitution of the Mexican United States written in 1824 following the overthrow of the Mexican Empire of Agustin de Iturbide in the Mexican War of Independence.

Read about General Teran, a Mexican general who fought for Mexican independence in the Mexican and Texan revolutions.

By the end of this section, you will be able to observe that motion in two dimensions consists of horizontal and vertical components and understand the independence of horizontal and vertical vectors in two-dimensional motion.

In this activity, students use TI-Interactive! or TI-83/84's to explore the independence of vertical and horizontal velocity components for swimmers crossing a river.

In this activity, students will apply the Chi Squared test for independence to a data set of high school AP Statistics Exam scores. They will set up a two-way table and calculate the chi squared test statistic by hand.

This set contains statistics questions about Venn diagrams. The student interprets when a Venn diagram suggests such event pairs as mutually exclusive, complementary, and independent events, and uses these diagrams in determining...

In this activity, students use a temperature sensor to measure the temperature of water samples before and after adding washing soda. They understand concepts of dependent and independent variables and study the relationship between them.

Students learn to solve a system of linear equations (2 equations with 2 variables) by substitution and elimination methods. They also review the definitions of consistent (independent and dependent) and inconsistent systems, and...

Students explore nonparametric tests for dependent and independent data samples.

Students use a Force Sensor to collect weight versus number data for a collection of identical pennies and model the data using a linear equation. They will then interpret the slope as it relates to independent and dependent variables.

Students understand how tests of significance can be performed with confidence intervals. They use a simulation to clarify the meaning of a hypothesis. Students examine large sample tests for a proportion, mean, difference between two...

Learn about the life of William B. Travis, a southern lawyer who died at the battle of the Alamo during the Texas Revolution. Includes a timeline.

This is the text of an address Austin made to the people of Louisville, Kentucky explaining the conflict between Texas and Mexico, and asking for support.

See the articles of the Treaty of Velasco reprinted in their entirety, which were written to be the first steps toward the official recognition of the Texas Republic's independence.

Why does Texas have a county called "Deaf Smith"? Discover this hero of Texas independence who was a hearing-impaired mounted scout during the struggle with Mexico.

Learn about one of the great founders of the state of Texas. Sam Houston led Texans through many difficult years and is rightfully remembered for his role in Texas' independence and statehood. (In Spanish)

Overview and detailed facts about the Texas Revolution that resulted in the establishment of the Republic of Texas.

In this learning module, students will learn and apply the concepts of author's style and syntax.

This lesson is about the proper use of subordinating conjunctions. You will learn to make your writing more interesting by using conjunctions, but you will specifically focus on subordinating conjunctions such as because, when, while.

PBS presents a biography on the life of Stephen Fuller Austin. Known as "The Father of Texas," Stephen F. Austin established the first Anglo-American colony in the Teas province of Mexico and saw it grow into an independent republic.
