Texas Gateway: Determining Intercepts and Zeros of Linear Functions

Keep your mathematicians engaged using this group linear functions activity. Each of ten groups receives two graphs with both an image and equation, as well as a "who has" phrase to call out the next graph. Scholars stay on their toes as...

High schoolers determine the linear equations of the density of water and oil by collecting data on the mass of various volumes of each liquid. They construct scatter plots from the data and use these to write the linear equations for...

Bring the video in tow when studying linear functions. Young pupils learn to apply linear functions to real-world contexts by watching a short instructional video. Given information about the cost of hiring a tow company, they create a...

The path to learning about linear functions is a straight line. Scholars first learn to connect the slope-intercept form of a linear function to features of its graph. They then see how to write a linear function given two points and to...

The student is expected to gather and record data & use data sets to determine functional relationships between quantities.

Given a graph or verbal description of a function, the student will determine whether the parent function is quadratic or linear.

Given a real-world situation that can be modeled by a linear function or a graph of a linear function, the student will determine and represent the reasonable domain and range of the linear function using inequalities.

Given algebraic, tabular, and graphical representations of linear functions, the student will determine the intercepts of the function and interpret the meaning of intercepts within the context of the situation.

Given verbal descriptions of situations involving systems of linear equations, the student will determine the reasonableness of the solutions to the system of equations.

Using rates from a rental car company, young mathematicians graph data, explore linear relationships, and discuss the role of slope and the y-intercept. This lesson allows for the discussion of independent and dependent variables, as...
