Algebra 1 - Writing Linear Equations

Updated: Nov 19, 2025

This post explains and gives practice opportunities related to TEKS A.2C:

write linear equations in two variables given a table of values, a graph, and a verbal description;

Instruction

Students learn two new formulas for linear functions, the point-slope form and the standard form. Using what they learned in 8th grade math about how to find the slope and how to write a linear function in slope-intercept form, students now explore how to write linear functions given a set of coordinates in tabular form.

Sometimes students are given a story problem and have to use that to generate an equation for a linear function in either slope-intercept or standard form.

STAAR Practice

Between 2016 and 2025 (including redesign practice), this readiness standard has been tested 20 times on the STAAR test. Videos explaining the problems can be found below. If you'd rather take a quiz over these questions, click here. The videos below are linked to the questions in the quiz as answer explanations after the quiz is submitted.
